We use GHRSST L4, QuikSCAT, OAFLUX and SeaWiFS L3 data sets to analyze the change of sea surface temperature (SST), sensible heat flux, latent heat flux and chlorophyll - a concentration in the equatorial ocean where Typhoon Vamei passed through. Before Typhoon Vamei was generated, there was a significant cyclonic vortex over the equatorial region of the southern South China Sea, the average SST in the coastal region of South China Peninsula was lower than other regions, and northeasterly wind prevailed in this area. The latent heat flux and sensible heat flux were larger in the genesis location of Typhoon Vamei . As usual, the cooling occurred on the right side of the track of Typhoon Vamei. The SST decreased by about 2 - 2.5 ℃ . However, compared to higher-latitude typhoons, the cooling was much small in this case. The region where SST decreased significantly was between the east of the Malay Peninsula and the Strait of Malacca. Similar to higher-latitude typhoons, Typhoon Vamei increased chlorophyll- a concentration in the coastal area between Sumatra and the Malay Peninsula by 0.6 mg·m - 3 or more compared to the pre-typhoon value.
