(a) Climatologic seasonal cycles of surface area where DC takes place (gray bars), model simulated surface chlorophyll-a (Chla) (black line), MODIS surface Chla (green line) and SeaWiFs Chla (magenta line). The inset show the scatter between the climatological values of model-computed Chla and the two different satellite-derived Chla products. (b) Time series of surface area where DC takes place (gray bars), model surface Chla (black line), MODIS surface Chla (green line) and SeaWiFs Chla (magenta line) for the period 2000–2015. The inset show the scatter between the model-computed Chla and the two different satellite-derived Chla products. (c) Scatter plot of the annual accumulated extension of the deep convection area (defined as the region where mixed layer depth > 1000 m) and the magnitude of the Chla bloom in the model (black symbols and line), MODIS (green symbols and line) and SeaWiFs (magenta symbols and line).
