There is pretty good correspondence between the two datasets, with LT having warm outliers during major El Ninos (especially 1987, 1998, 2010, and 2024). This behavior is due to extra heating of the troposphere (which LT measures) during El Nino by enhanced deep moist convection in the tropics when the tropical Pacific Ocean surface warms from reduced upwelling of cold water from below, an effect exaggerated by the several-month lag of tropospheric warming behind surface warming during El Nino:<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure
