A study shows that assimilating high- temporal- resolution wind profile data from the PANSY radar at Japan’s Syowa Station in Antarctica improves reanalyses and forecasts of atmospheric rivers (ARs) in the Southern Hemisphere.

The paper, “Impact of Antarctic radar on Southern Hemisphere atmospheric river reanalysis and forecast,” was published in Scientific Reports.

Observational sparsity over Antarctica and the Southern Ocean reduces forecast skill for Southern Hemisphere atmospheric circulation compared with the Northern Hemisphere. Conventional radiosondes help but are limited in frequency due to cost and logistics.

Observational sparsity over Antarctica and the Southern Ocean reduces forecast skill for Southern Hemisphere atmospheric circulation compared with the Northern Hemisphere. Conventional radiosondes help but are limited in frequency due to cost and logistics.

The study used a data assimilation system to test the impact of hourly horizontal wind profiles (roughly 1.5-20 km altitude) from the Program of the Antarctic Syowa Mesosphere- Stratosphere- Troposphere/Incoherent Scatter (PANSY) radar at Syowa Station (69°S, 39.6°E). Experiments covered periods including the 2022 Year of Polar Prediction in the Southern Hemisphere (YOPP- SH) extra radiosonde campaign.

They compared reanalyses and forecasts with vs. without the PANSY data (and relative to products like ERA5).

Main findings

  • Assimilating PANSY data changes initial atmospheric conditions for forecasts, even when extra YOPP-SH radiosondes are already included. These differences persist over Antarctica and the Southern Ocean.
  • The data improves the representation of the atmospheric basic state (wind speed, temperature, and geopotential height) at high latitudes.
  • It enhances prediction of atmospheric circulation and integrated water vapor (and related integrated vapor transport) associated with mid- latitude ARs in the Southern Hemisphere. In related analyses, including PANSY data reduced root- mean- square errors in forecasts of AR-related fields relative to ERA5 for multiple mid- latitude cases, and increased analyzed IVT in some East Antarctic interior regions where ARs occur.

ARs are long, narrow corridors of strong moisture transport that can deliver heavy precipitation and affect weather extremes. Better initial conditions over the data-sparse polar region help downstream forecasts because errors can propagate equatorward.

The results highlight the value of continuous, high- resolution radar wind observations from Antarctica for numerical weather prediction, beyond what infrequent radiosondes alone provide. The work was supported by Japan’s National Institute of Polar Research, JSPS grants, and the Japanese Antarctic Research Expedition, with experiments run on the Earth Simulator at JAMSTEC.

Southern Ocean weather patterns are among the most intense and continuous on Earth. This vast, nearly land- free expanse (roughly south of 30- 40°S, encircling Antarctica) features strong, persistent westerly winds, frequent extratropical cyclones, and major influences from large- scale climate modes. These patterns drive the powerful Antarctic Circumpolar Current (ACC), shape precipitation and sea ice, and play a critical role in global heat, moisture, and carbon transport.

Dominant Features

Strong westerly winds (“Roaring Forties,” “Furious Fifties,” and “Screaming Sixties”): Uninterrupted by major landmasses, these winds are the strongest mean surface winds on Earth. They drive the ACC (the world’s strongest ocean current) eastward and generate large waves and storminess.

Storm track and extratropical cyclones: A band of high storm activity lies roughly between 40°- 60°S. Cyclones form frequently due to the strong meridional temperature gradient and baroclinic instability associated with the subpolar jet. These systems bring high winds, clouds, and precipitation, and they modulate heat and moisture transport.

Circumpolar trough: A belt of low pressure surrounds Antarctica, with mean sea- level pressures often below 990 hPa. This feature shows a clear semiannual oscillation.

Precipitation patterns: Precipitation tends to increase poleward and decrease at lower latitudes in recent decades (consistent with climate change projections). Storms are producing more rain in some areas, for example, observations at Macquarie Island (in the storm track) show a ~28% rainfall increase since 1979, largely because individual storms drop more precipitation rather than because there are simply more storms.

Key Climate Modes Influencing Variability

Southern Annular Mode (SAM / Antarctic Oscillation): The leading mode of variability. In its positive phase, the westerly wind belt intensifies and contracts southward toward Antarctica (stronger high- latitude winds, often linked to reduced rainfall in parts of southern Australia and changes in Antarctic sea ice and ice- shelf melt via upwelling). In its negative phase, the belt shifts equatorward. Positive SAM has become more frequent in recent decades, partly due to ozone depletion and greenhouse- gas forcing.

El Niño- Southern Oscillation (ENSO): Influences the Southern Ocean via teleconnections (e.g., deepening or weakening of the Amundsen Sea Low). La Niña often enhances certain storm patterns and can interact with positive SAM.

Amundsen Sea Low: A persistent low-pressure feature in the South Pacific sector that strongly affects West Antarctic and Peninsula weather, sea ice, and temperatures.

Other influences include the Interdecadal Pacific Oscillation and blocking highs that can steer moisture toward Antarctica.

Atmospheric Rivers (ARs)

Narrow corridors of intense moisture transport frequently occur over the Southern Ocean (especially 40°- 60°S). They are often embedded ahead of extratropical cyclone cold fronts and can extend toward Antarctica, delivering heat, moisture, and heavy precipitation or snowfall.

ARs contribute significantly to extreme precipitation events and can influence Antarctic surface mass balance (snowfall vs. melt). Recent studies (including those using Antarctic radar data such as PANSY) show that better observations improve forecasts of these systems and related mid-latitude circulation.

AR frequency has shown poleward shifts and increases over the Southern Ocean in recent decades, modulated by both circulation changes (jet shifts) and rising atmospheric moisture.

Seasonal and Regional Aspects

Seasonality: Stronger storms and higher precipitation in winter (JJA) at mid- latitudes in many sectors; more complex patterns near Antarctica involving sea- ice interactions.

Regional differences: The Pacific, Atlantic, and Indian Ocean sectors of the Southern Ocean show longitudinal variations due to the influence of South America, Africa, Australia, and the Antarctic Peninsula. Hotspots for marine heatwaves and cyclone activity exist in areas such as the western Pacific and North Ross Sea sectors.

Sea ice interactions: Expanding/contracting Antarctic sea ice strongly modulates surface fluxes, storm tracks, and cyclone intensity. Recent years have seen record- low sea- ice extents linked to atmospheric anomalies (e.g., deep Amundsen Sea Low).

Broader Climate Role and Changes

The Southern Ocean absorbs a large fraction of anthropogenic heat (~75%) and carbon (~35- 50%). Weather patterns (especially winds and storms) drive the meridional overturning circulation (upper and lower cells), upwelling of deep water, and formation of key water masses (e.g., Antarctic Bottom Water, Intermediate Water).

Observed trends include:

  • Strengthening and poleward shift of the westerlies (linked to positive SAM trends).
  • Increasing storm-related rainfall and freshwater input.
  • Rising marine heatwave activity in some regions.
  • Complex interactions with Antarctic ice-sheet mass balance via ARs, snowfall, and warm-water upwelling.

Data sparsity remains a challenge (few islands and stations), so reanalyses, satellite data, and special observing campaigns (e.g., YOPP- SH) plus Antarctic radar observations are especially valuable for improving forecasts of these patterns and associated extremes.

In short, Southern Ocean weather is characterized by relentless westerlies, frequent intense cyclones, moisture- laden atmospheric rivers, and strong modulation by the SAM and tropical teleconnections, making it both a driver of global climate and a sensitive indicator of change.

Impact of Antarctic radar on Southern Hemisphere atmospheric river reanalysis and forecast

Observational sparsity over Antarctica and the Southern Ocean leads to lower forecast skill for Southern Hemisphere (SH) atmospheric circulation than in the Northern Hemisphere. Extra radiosonde observations help, but their frequency is limited by cost and logistics.

Using a data assimilation system, the authors tested the impact of hourly wind profiles from the PANSY radar (Program of the Antarctic Syowa Mesosphere–Stratosphere–Troposphere/Incoherent Scatter radar) at Japan’s Syowa Station. Assimilating these data changes the initial atmospheric conditions for weather forecasts, even when extra radiosonde data from the 2022 Year of Polar Prediction in the Southern Hemisphere (YOPP- SH) campaign are already included. The differences persist over Antarctica and the Southern Ocean.

The high- temporal- resolution Antarctic radar data improves:

  • Reproducibility of the atmospheric basic state (wind speed, temperature, and geopotential height) at high latitudes.
  • Prediction of atmospheric circulation and integrated water vapor associated with atmospheric rivers (ARs) over mid- latitude regions of the SH.

Additional context from the paper

ARs are narrow, long corridors of intense water- vapor transport linked to severe weather (strong winds, heavy precipitation, flooding). They contribute substantially to extreme precipitation in parts of the SH, including New Zealand, Australia, Antarctic coastal regions, and South America, and can drive strong winds, surface melting, temperature rises, and heavy snowfall in Antarctica.

Previous work already showed benefits of PANSY wind data for mid- latitude cyclone forecasts. This study focuses on ARs during the 2022 austral winter YOPP- SH period (extra radiosondes at various SH stations).

Experiments used the ALEDAS3 ensemble data assimilation system. They compared a control reanalysis (CTL, using standard PREPBUFR observations) with one that also assimilated hourly PANSY winds (OSEP) for the period ~26 April- 5 September 2022.

Mean absolute differences in wind speed, geopotential height, and temperature (700- 200 hPa) between OSEP and CTL were notable over parts of the Southern Ocean and Antarctica. These differences could propagate and amplify downstream with the jet stream.

The authors examined AR frequency and integrated water vapor transport (IVT) reproducibility, finding impacts on both reanalysis and forecasts of mid- latitude ARs.

Abstract

Observational data sparsity in Antarctica and the Southern Ocean results in lower forecast skill for atmospheric circulation over the Southern Hemisphere (SH) than the Northern Hemisphere. Additional Antarctic radiosonde observations at existing observation stations can enhance accurate forecasting of severe events over the SH; however, the number of daily radiosonde observations is limited, owing to financial and operational limitations. Using a data assimilation system, this study investigates the impact of hourly wind profiles from the PANSY radar at the Japanese Antarctic Syowa Station. Assimilation of PANSY data leads to differences in the initial atmospheric conditions for weather forecasts, even including extra radiosonde observations from the Year of Polar Prediction in the Southern Hemisphere (YOPP-SH) campaign in 2022. These differences in initial atmospheric condition persist in Antarctica and the Southern Ocean. We show that Antarctic radar data with relatively high temporal resolution has an impact on the reproducibility of atmospheric basic state (wind speed, temperature and geopotential height) over the high latitudes and the prediction of atmospheric circulation and integrated water vapor associated with atmospheric rivers over the mid latitude in SH.

Why do Atmospheric Rivers Occur?

A significant atmospheric river event will occur tomorrow (Sunday) and Monday, with heavy precipitation in the mountains and South Sound.

A significant atmospheric river event will occur tomorrow (Sunday) and Monday, with heavy precipitation in the mountains and South Sound.

The latest UW WRF model forecast predicts up to 10 inches in the Cascades, with the southern WA Cascades being hit the hardest (see below).   In contrast, a profound rain shadow will extend from the NE Olympics to Bellingham. 

It is now clear that there will be some serious flooding in some locations. For example, the NOAA/NWS River Forecast Center is forecasting major flooding on the Snoqualmie River near Carnation.   

Want to see something spectacular?   Go to Snoqualmie Falls on Monday.  If you can get there.😁

Atmospheric rivers in our region are associated with plumes of warm, moist air from the south, southwest, and west.

NOAA weather satellites can sense the water vapor, which is very evident in the water vapor image from this morning (below).  A massive plume of water vapor is moving our way.

Numerical weather prediction models, like the UW WRF model, can skillfully forecast such water vapor plumes, which release massive amounts of water as the air is forced to rise by our region’s substantial terrain.

Meteorologists favorite diagnostic for atmospheric rivers is integrated water vapor transport (IVT), which is the amount of water vapor times the wind speed, summed up in the vertical (that is where the integrated comes from).   This quantity is more closely related to the potential for regional rainfall.

The prediction of IVT for Sunday morning is shown below, with the arrows showing both the direction and magnitude of the moisture transport   Large values, but not record-breaking by any means.  

Such moisture plumes are generally warm as well.   In fact, to get large values they HAVE to be warm since the amount of moisture air can hold depends on temperature (warm air can potentially hold more water vapor than cold air).

Atmospheric rivers form in our region when strong southwesterly atmospheric wind currents occur, currents that move large values of water vapor out of the subtropics.

The atmospheric flow pattern that does this is usually characterized by a strong low-pressure area in the Gulf of Alaska and higher pressure west of southern California.

Not surprisingly, this is exactly the pattern forecast for Sunday morning at 10 AM for a level around 5000 ft (below).  With high pressure to the south and low pressure to the northwest, a strong pressure/height change is created, which produces a strong southwesterly flow. 

The interesting thing about atmospheric rivers is that they are like regular rivers in another way…not only does water come into the river at the beginning, but there is a convergence of water vapor from the sides along the way, not unlike the small streams that drain into a river over its entire path.

The Overlooked Role of Atmospheric Rivers in Arctic Sea Ice Loss: A Challenge to the CO2-Centric Narrative

The study on atmospheric rivers has given us a valuable insight into the complexity of Arctic sea ice variability. The role of ARs in both ice melt and recovery provides a clear challenge to the simplistic view that Arctic changes are primarily driven by CO2 levels. This should prompt us to rethink the way we approach climate science and, more importantly, climate policy.

From Watts Up With That?

By Charles Rotter

The dominant narrative in climate science holds that Arctic sea ice loss is almost entirely driven by human-induced global warming, primarily from CO2 emissions. Yet, a Nature Communications study titled Role of Atmospheric Rivers in Shaping Long-Term Arctic Sea Ice Variability highlights a crucial factor that has been largely overlooked: atmospheric rivers (ARs). These ARs—narrow, intense streams of water vapor originating in tropical and mid-latitude regions—play a significant role in Arctic sea ice variability, a phenomenon that traditional climate models fail to adequately capture.

By concentrating so heavily on CO2 as the main culprit of Arctic sea ice decline, mainstream climate models ignore the complex interactions between natural atmospheric phenomena and sea ice variability. This omission exposes the significant limitations in our understanding of the Arctic’s climate, and by extension, the reliability of the climate models driving current policy.

What Are Atmospheric Rivers, and Why Are They Important?

Atmospheric rivers are immense, fast-moving channels of water vapor that can transport moisture across vast distances. These rivers are known for delivering enormous quantities of water in the form of rain or snow when they make landfall, but their influence on the Arctic is less understood. The Nature Communications study shows that ARs can have a profound impact on the Arctic’s sea ice cover, both in terms of accelerating melt and contributing to periods of ice recovery.

These atmospheric rivers inject warm, moist air into the Arctic, which increases the temperature in the region and melts sea ice. The moisture they bring also plays a significant role in cloud formation, which in turn affects the energy balance of the Arctic system. Yet, despite this, ARs are often left out of the conversation when discussing Arctic ice loss, as the focus remains firmly fixed on CO2 emissions. This begs the question: why are such natural forces so often ignored in the narrative?

Abstract

Atmospheric rivers (ARs) reaching high-latitudes in summer contribute to the majority of climatological poleward water vapor transport into the Arctic. This transport has exhibited long term changes over the past decades, which cannot be entirely explained by anthropogenic forcing according to ensemble model responses. Here, through observational analyses and model experiments in which winds are adjusted to match observations, we demonstrate that low-frequency, large-scale circulation changes in the Arctic play a decisive role in regulating AR activity and thus inducing the recent upsurge of this activity in the region. It is estimated that the trend in summertime AR activity may contribute to 36% of the increasing trend of atmospheric summer moisture over the entire Arctic since 1979 and account for over half of the humidity trends in certain areas experiencing significant recent warming, such as western Greenland, northern Europe, and eastern Siberia. This indicates that AR activity, mostly driven by strong synoptic weather systems often regarded as stochastic, may serve as a vital mechanism in regulating long term moisture variability in the Arctic.

The Complexity of Arctic Sea Ice Variability

One of the most valuable contributions of this study is how it emphasizes the complexity of Arctic sea ice variability. The study documents that atmospheric rivers play a dual role in the Arctic: at times, they can melt sea ice by delivering heat, while in other instances, they help stabilize or even recover sea ice under certain conditions. This nuanced effect is vital to understanding why Arctic ice levels are not following the simplistic, linear trajectory of decline that CO2-centric climate models predict.

For example, in years with fewer or weaker atmospheric rivers, sea ice can recover, even in the context of an overall warming trend. Conversely, strong or frequent AR events can lead to accelerated ice loss. This dynamic, episodic interaction starkly contrasts with the popular portrayal of Arctic sea ice loss as an inevitable, unidirectional consequence of increasing CO2 levels. Instead, it points to a system where natural variability and short-term weather events play as significant a role as long-term climate trends.

The Limitations of Current Climate Models

The study’s findings expose significant deficiencies in the climate models that underpin much of the global warming narrative. These models, which are the foundation for policies like Net Zero and the Green New Deal, are primarily driven by the assumption that rising CO2 levels are the dominant force behind climate change. Yet, as the Nature Communications study reveals, atmospheric rivers—completely unrelated to CO2 emissions—are major drivers of Arctic sea ice variability.

Why do current climate models fail to account for such phenomena? The answer lies in the inherent limitations of these models. Climate models are built on assumptions and simplifications that struggle to accurately capture complex, chaotic atmospheric interactions like ARs. As a result, their projections tend to overestimate the impact of CO2 and underestimate or outright ignore natural variability.

This creates a problematic situation where policymakers are making decisions based on incomplete or faulty data. If atmospheric rivers, which are unpredictable and chaotic, can exert such a significant influence on the Arctic, it calls into question the reliability of long-term projections made by models that neglect them.

Natural Variability: A Long-Ignored Factor

The role of natural variability in shaping the Arctic’s climate is another critical point highlighted by the Nature Communications study. Arctic sea ice levels have fluctuated significantly in the past, long before the industrial era. Periods of Arctic warming in the early 20th century, for example, occurred with no significant rise in CO2 levels, pointing to the influence of natural climate drivers, including atmospheric rivers and oceanic cycles.

This should make us question why modern climate science tends to downplay or ignore the role of natural variability in current climate trends. The idea that CO2 is the singular driving force behind Arctic changes is not supported by historical evidence. The Arctic has always been subject to complex interactions between atmospheric and oceanic forces, and atmospheric rivers are just one example of such natural drivers.

Yet, today’s climate models tend to gloss over these complexities, focusing instead on greenhouse gas emissions as the primary explanatory variable. This not only leads to inaccurate predictions but also promotes a one-dimensional understanding of climate dynamics, particularly in the Arctic.

ARs, which can cause rapid and extreme moisture surges, may lead to significant Arctic melt events and initiate positive feedback loops. Future studies are essential to explore these potential new roles of ARs in AA as the Arctic continues to warm.

Arctic Sea Ice Recovery: An Inconvenient Truth

Another inconvenient fact often omitted from the CO2-driven narrative is the occasional recovery of Arctic sea ice. While it’s true that there has been a long-term decline in sea ice, periods of recovery—such as those observed after the dramatic low in 2012—undermine the idea of a linear decline. The Nature Communications study suggests that atmospheric rivers can create conditions conducive to ice recovery, depending on their timing and intensity.

For example, a lower-than-average occurrence of ARs in certain years has allowed for the temporary recovery of Arctic sea ice. This goes against the projections of climate models that had forecast an ice-free Arctic by now. It turns out the Arctic is more resilient than many alarmist predictions would have us believe, largely because these predictions fail to consider the full range of forces—like ARs—that influence ice variability.

This raises an important point: how reliable are the models if they cannot account for the natural forces that occasionally lead to sea ice recovery? This is not just an academic question—it has serious implications for the climate policies being pursued around the world today.

Questioning Drastic Climate Policies

Given the findings of the Nature Communications study, it becomes increasingly difficult to justify the extreme climate policies being advocated by governments and international organizations. The Net Zero agenda, which seeks to eliminate all carbon emissions, is premised on the idea that human-induced CO2 is the primary driver of climate change. But if natural variability, including phenomena like atmospheric rivers, plays a significant role in climate dynamics, then the rationale for these policies becomes less clear.

This doesn’t just affect scientific debates—it has real-world consequences. The costs of achieving Net Zero, in terms of both economic disruption and environmental degradation from mining for rare earth metals for renewable technologies, may far outweigh the supposed benefits. Worse, by focusing on CO2 reduction as the sole solution, these policies ignore more practical, adaptive strategies that could better help societies cope with the impacts of climate change—whatever its causes.

The Unsettled Science of the Arctic

Ultimately, the Nature Communications study serves as a reminder that the science of the Arctic, and by extension, climate change as a whole, is far from settled. Atmospheric rivers, oceanic cycles, and other natural phenomena play significant roles in shaping the Earth’s climate, yet they are often ignored in favor of simplistic, politically convenient narratives centered around CO2 emissions.

The failure to adequately model and predict the influence of ARs on Arctic sea ice is just one example of how climate science still has much to learn. Policymakers should take heed: enacting drastic climate measures based on incomplete or inaccurate models could do more harm than good.

The lesson here is one of humility. The Earth’s climate is a complex, dynamic system with many interacting parts. By reducing it to a single variable—CO2—we risk not only misunderstanding the problem but also implementing ineffective and potentially harmful solutions.

As the Nature Communications study shows, the influence of atmospheric rivers on Arctic sea ice variability is a critical factor that cannot be ignored. It’s time we move beyond the oversimplified, CO2-centric models and embrace a broader, more nuanced understanding of the forces at play in our climate system.

Conclusion: A Call for Rethinking Climate Models and Policies

The study on atmospheric rivers has given us a valuable insight into the complexity of Arctic sea ice variability. The role of ARs in both ice melt and recovery provides a clear challenge to the simplistic view that Arctic changes are primarily driven by CO2 levels. This should prompt us to rethink the way we approach climate science and, more importantly, climate policy.

By acknowledging the limitations of current models and embracing a more holistic understanding of climate dynamics, we can develop more effective, adaptive strategies that better serve both the environment and humanity. The Arctic’s fate is not as straightforward as many would have us believe, and neither should be the policies we enact in response to its changes.
