摘　　要：该文选择2013年9月登陆汕尾的台风“天兔”,结合卫星遥感观测资料、HYCOM海洋环流模式结果、Argo浮标实测数据,分析了台风“天兔”过境期间对粤东及附近海域海洋环境的影响过程,借此提高对粤东及附近海域上层海洋物理环境对台风响应的认识。结果表明:台风“天兔”路径右侧,靠近吕宋海峡东面的位置引起了一个降温中心,由于粤东海域海洋热容量较低,所以“天兔”在穿过吕宋海峡进入粤东海域后,没有获得足够的能量以维持其发展,进而强度降低,其过境期间也引起了海洋次表层的暖异常。“天兔”过境引起粤东海域叶绿素变化存在一定的延迟响应,叶绿素浓度增长率与台风移动速度呈一定的负相关,与台风强度呈正相关。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.
