Abstract
In this paper,Typhoon Usagi,which landed in Shanwei in September 2013,is selected and combined with satellite remote sensing observation data,HYCOM ocean circulation model results,and Argo float measured data,to analyze the process of influence of Typhoon Usagi on the Marine environment in eastern Guangdong and the nearby waters during its transit,so as to improve the understanding of the response of upper Marine physical environment in eastern Guangdong and the nearby waters to typhoon.The results show that the right side of Typhoon Usagi's path,near the east of the Luzon Strait,caused a cooling center.Due to the low ocean heat capacity in the East Guangdong waters,Typhoon Usagi did not obtain enough energy to maintain its development after crossing the Luzon Strait into the East Guangdong waters,and then its intensity decreased.During its transit,it also caused a warming anomaly in the ocean subsurface.There was a delayed response to the change of chlorophyll a in the east Guangdong sea area caused by the transit of Typhoon Usagi.The growth rate of chlorophyll a concentration was negatively correlated with the moving speed of typhoon and positively correlated with the intensity of typhoon.关键词
