Column-Average Tropospheric Temperature Anomaly over the Tropics

This is a map of monthly tropospheric temperature anomaly in the global tropics, averaged from 850 hPa to 200 hPa.

Yellow to red colors represent positive temperature anomalies, and blue colors represent negative temperature anomalies. The climatological base period used to calculate the anomalies is 1991-2020. Temperature anomalies are contoured at an interval of 0.5°C
