Figure 12 Seasonal bias in downwelling surface short wave radiation in (left) CCSM4 and (right) CAM4/AMIP. CINT=20 Wm-2, positive/negative values are shown by solid/dashed, respectively. Zero contour is not shown. The PIRATA mooring 10oW, 10oS location is marked by ‘+’.
Figure 14 Seasonal cycle of latent heat flux (LHTFL, Wm-2) at 10oW, 10oS from IFREMER satellite retrievals of Bentamy et al. (2008), from the PIRATA mooring, and simulated by CCSM4 and CAM4/AMIP. Observed LHTFL is calculated from the buoy data using the COARE3.0 algorithm of Fairall et al. (2003).
