Figure 1. Scatterplot of evaporative cooling versus sea surface temperature. Evaporative cooling is calculated from TRMM satellite-observed rainfall data. Each dot is a 1° latitude x 1° longitude ocean surface gridcell. The conversion factor from rainfall to evaporation is that 80 watts per square metre (W/m2)…
