WARMER DOWN SOUTH. The second panel of this multi-year plot built from TES data shows (reddish tints) that the atmosphere over southern latitudes is warmer in southern hemisphere summer than the atmosphere over the equivalent northern latitudes in northern summer. Also note the year-to-year variations. Click on the image to download a larger version. NASA/JPL/Arizona State University
