This change strengthened its lagged (delayed) influence on Antarctic summer sea ice, particularly in the <strong>Weddell Sea<\/strong> and <strong>Ross Sea <\/strong>regions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Southern Annular Mode (SAM)<\/strong>, also called the <strong>Antarctic Oscillation (AAO)<\/strong>, is the dominant mode of atmospheric variability in the Southern Hemisphere extratropics (south of about 20\u00b0S). It explains a large portion (~30%) of climate variability in this region and primarily describes changes in the strength and north-south position of the circumpolar westerly winds (the polar jet stream).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">SAM is quantified as the normalized difference in zonal-mean sea-level pressure (SLP) between mid-latitudes (~40\u00b0S) and high latitudes (~65\u00b0S, around Antarctica):<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Positive SAM: <\/strong>Lower pressure over Antarctica + higher pressure in mid-latitudes \u2192 stronger, more poleward-shifted westerlies.<\/li>\n\n\n\n<li><strong>Negative SAM:<\/strong> Higher pressure over Antarctica + lower pressure in mid-latitudes \u2192 weaker, more equatorward westerlies.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">It is often measured using:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Station-based indices (e.g., Marshall index from observations at ~40\u00b0S and 65\u00b0S).<\/li>\n\n\n\n<li>Reanalysis-based principal component (PC1) of SLP or geopotential height anomalies.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The SAM index is currently positive (as of 13 June 2026) but is forecast to return toward neutral by late June.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Researchers used techniques like <strong>running empirical orthogonal function (EOF) analysis<\/strong> and <strong>k-means clustering <\/strong>on reanalysis data to detect this structural regime shift around 1998.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This 1998 shift is a subtle but important change in how the SAM operates in spring, rather than just its overall strength (though the SAM has also shown long-term positive trends linked to ozone depletion and greenhouse gases).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">_____________________________________________________________________________________<\/p>\n\n\n\n<p class=\"has-large-font-size wp-block-paragraph\"><strong>Interdecadal shift in the spring Southern Annular Mode intensifies its lagged influence on Antarctic summer sea ice<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Paper Title:<\/strong> Interdecadal shift in the spring Southern Annular Mode intensifies its lagged influence on Antarctic summer sea ice<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Authors:<\/strong> <a href=\"javascript:;\">Juan Dou<\/a>,&nbsp; <a href=\"javascript:;\">Xiangzhou Song<\/a> (Hohai University), <a href=\"javascript:;\">Renhe Zhang<\/a> (Fudan University), et al.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Journal:<\/strong> National Science Review (Advance Article) <a href=\"https:\/\/www.eurekalert.org\/releaseguidelines\">Peer-Reviewed Publication<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>DOI: <\/strong><a href=\"http:\/\/dx.doi.org\/10.1093\/nsr\/nwag314\" target=\"_blank\" rel=\"noopener\">10.1093\/nsr\/nwag314<\/a> (Published online ~May\/June 2026)<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Open Access?<\/strong> Likely (common for NSR advance articles)<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Abstract<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Antarctic sea ice has recently shifted to a new low-extent regime, yet the underlying mechanisms remain uncertain. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This study reveals an interdecadal shift in the spring Southern Annular Mode (SAM) pattern around 1998, after which its lagged influence on summer Antarctic sea ice intensified, particularly in the Weddell and Ross Seas. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">After 1998, the SAM exhibits stronger wave-like structures, featuring an intensified Pacific\u2013South American (PSA)-like pattern that drives regional sea-ice loss. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In the Weddell Sea, the positive SAM\u2011related anticyclonic circulation induces upper-ocean warming that promotes summer ice melt. However, in the Ross Sea, a deepened Amundsen Sea low enhances offshore ice export and positive ice\u2011albedo feedback, increasing summer ice loss. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This interdecadal SAM shift is likely modulated by tropical variability, as the increased co-occurrence of a positive SAM with La Ni\u00f1a strengthens PSA-mediated processes. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">These findings highlight the nonstationary nature of tropical\u2013polar linkages in recent Antarctic sea-ice lows.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">______________________________________________<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This study reveals an <strong>interdecadal shift<\/strong> in the spring <strong>Southern Annular Mode (SAM)<\/strong> pattern around <strong>1998<\/strong>. After this shift, the spring SAM&#8217;s <strong>lagged influence<\/strong> on Antarctic summer sea ice became significantly stronger, especially in the Weddell Sea and Ross Sea sectors.<\/p>\n\n\n\n<p class=\"has-medium-font-size wp-block-paragraph\"><strong>Main Findings<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Pre-1998 vs. Post-1998<\/strong>: <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Before ~1998, the connection between spring SAM and the following summer sea-ice extent was weak. After 1998, the SAM pattern developed <strong>stronger wave-like (zonal wave-3) features<\/strong>, making it more effective at influencing summer sea ice.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>The strengthened SAM<\/strong> became more tightly coupled with the <strong>Pacific-South American (PSA)<\/strong> teleconnection pattern and the Amundsen Sea Low (ASL).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This change enhanced <strong>preconditioning effects<\/strong> from spring into summer through both dynamic (ice transport) and thermodynamic (heat exchange, albedo feedback) processes.<\/p>\n\n\n\n<p class=\"has-medium-font-size wp-block-paragraph\"><strong>Regional Mechanisms (Post-1998)<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Weddell Sea:<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Positive spring SAM alters circulation, leading to persistent upper-ocean warming that reduces sea ice the following summer.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Ross Sea:<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Deeper ASL strengthens offshore winds\/ice transport in spring \u2192 more open water \u2192 increased solar absorption in summer \u2192 strong ice-albedo feedback amplifying melt.<\/p>\n\n\n\n<p class=\"has-medium-font-size wp-block-paragraph\"><strong>Role of ENSO<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The shift coincides with changes in SAM\u2013ENSO interactions. Positive SAM events have more often aligned with <strong>La Ni\u00f1a <\/strong>conditions since the late 1990s, amplifying tropical-extratropical teleconnections. This helps explain extreme low sea-ice events (e.g., record lows in Feb 2022 and 2023) following strong positive spring SAM + La Ni\u00f1a.<\/p>\n\n\n\n<p class=\"has-medium-font-size wp-block-paragraph\"><strong>Implications<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The SAM\u2013sea ice relationship is <strong>non-stationary <\/strong>(changes over decades), which has important consequences for predictability and climate model performance.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Improved representation of SAM&#8217;s structural changes, ASL dynamics, and SAM\u2013ENSO coupling is needed in models.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Helps explain recent dramatic Antarctic sea-ice declines beyond simple linear trends.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The ASL has shown a notable deepening trend in recent decades (especially since the 1970s\/1980s), linked to positive SAM trends, ozone changes, and greenhouse gases. This has been implicated in regional warming, sea ice changes, and accelerated ice loss in West Antarctica. However, the relationship is non-stationary and modulated by natural variability.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The ASL is a critical &#8220;control knob&#8221; for West Antarctic climate. Its dynamics illustrate the complex interplay between global modes (SAM, ENSO), anthropogenic forcing, and regional feedbacks. In the specific context of the spring SAM shift you asked about earlier, the strengthened coupling to the ASL post-1998 helps explain amplified lagged effects on summer sea ice loss through enhanced dynamic and thermodynamic processes.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>This study reveals an interdecadal shift in the spring Southern Annular Mode (SAM) pattern around 1998.
