The typhoon Wind-Pump induced upwelling and cold eddy often promote the significant growth of phytoplankton after the typhoon. However,
the importance of eddy-pumping and wind-driven upwelling on the sea surface chlorophyll a concentration (Chl-a) during the typhoon are
still not clearly distinguished. In addition, the air-sea heat flux exchange is closely related to the upper ocean processes, but few
studies have discussed its role in the sea surface Chl-a variations under typhoon conditions. Based on the cruise data, remote sensing
data, and model data, this paper analyzes the contribution of the vertical motion caused by the eddy-pumping upwelling and Ekman pumping
upwelling on the surface Chl-a, and quantitatively analyzes the influence of air-sea heat exchange on the surface Chl-a after the
typhoon Linfa over the northeastern South China Sea (NSCS) in 2009. The results reveal the Wind Pump impacts on upper ocean processes:
(1) The euphotic layer-integrated Chl-a increased after the typhoon, and the increasing of the surface Chl-a was not only the uplift
of the deeper waters with high Chl-a but also the growth of the phytoplankton; (2) The Net Heat Flux (air-sea heat exchange) played a
major role in controlling the upper ocean physical processes through cooling the SST and indirectly increased the surface Chl-a until
two weeks after the typhoon; (3) the typhoon-induced cyclonic eddy was the most important physical process in increasing the surface
Chl-a rather than the Ekman pumping and wind-stirring mixing after typhoon; (4) the spatial shift between the surface Chl-a blooms and
the typhoon-induced cyclonic eddy could be due to the Ekman transport; (5) nutrients uplifting and adequate light were two major
biochemical elements supplying for the growth of surface phytoplankton.
