Figure 1. Spatial patterns of (a-c) the diurnal phase (timing of the daily maximum and minimum values) and amplitude of latent heat flux, (d) diurnal amplitude of sea surface skin temperature, and (e) magnitude of surface wind speed over the tropical oceans. Gray contours denote satellite-derived annual mean sea surface temperature (°C, c) and wind speed (m s^-1, d-e).

Figure 2. (a) Total effect of diurnal variability on climatological latent heat flux, and (b-c) individual contributions of diurnal variations in sea surface skin temperature (SSTskin) and wind vector and (d-e) their percentages to the total effect. Dots (triangles) in (d) and (e) denote the regions where the contributions of diurnal wind variability are greater (smaller) than diurnal SSTskin variability. Contours denote satellite-derived surface precipitation rate (mm day^-1) in (a) and (c-e), and SST (°C) in (b).

Figure 3. (a) Power function relationship between the diurnal SSTskin-associated contribution to the climatological latent heat flux and surface mean wind speed, and (b) linear relationship between the diurnal SSTskin-associated contribution and surface wind speed enhancement over the GTMBA sites from buoy observations. (c) Total contribution from diurnal variability over the GTMBA sites from buoy observations and a regression model.
