Fig. 5: Linear trends of potential temperature at different pressure levels and regions.
From: The southward shift of hurricane genesis over the northern Atlantic Ocean
The linear trend of potential temperature (K year−1) at a 200 hPa and b 850 hPa. c The vertical profile of the linear trend of potential temperature (K year−1) averaged at the tropical region (10°S-5°N, 10°-80°W) (dashed blue line) and the subtropical region (15°N-30°N, 10°-80°W) (solid red line) (purple boxes of (a, b)). The purple boxes are the same as those in Fig. 3a.
