Red arrows in A1 and A2 show a patch of high chl-a concentration increasing towards the southwest. Red arrows in B1 and B2 show that low SST is detected in the same region of high chl-a during the northeast monsoon. Red circles in B3 and B4 show that the water temperature in this region was influenced by the Red River discharge in spring and summer. The black arrow in B4 shows a low SST region southwest of Hainan Island in summer.
