摘　　要：根据大亚湾海洋生态零点调查获得的水温、海流、潮位和气象观测资料，分析了1987年8月间大亚湾对8708和8710号台风的综合响应。结果显示，台风期间除增水外，整个大亚湾的水文结构因台风的影响发生了显著变化。其主要特征表现为：湾内垂直环流改变，海水层化消失，以及总体水温升高。分析表明，台风作用下垂直环流的调整可能是造成台风过程中大亚湾层化消失、总体水温升高的重要因素，而陆地边界的存在显然改变了海洋对热带风暴的响应特征。Based on observations of current and temperature profile from mooring arrays deployed in the Daya Bay in 1987, and those of tides and meteorological parameters from coastal sta tions, response of hydrological conditions of The Bay to typhoons No. 8708 and No. 8700 were analyzed. Results show that other than barotropic surges caused by typhoons,the baro cllnic structure of the whole Bay changed dramatically because of passage of the two ty phoons, although both typhoon moved westward across the South China sea about 800km south off the southern China coasts. The major response in the Daya Bay appeared to be:re versal of the normal summer upwelling circulation ; destratification of the vertical stratified temperature structure; and rising of bulk water temperature. It is likely that adjustment of vertlcal circulation during typhoon passage plays a important role in causing destratification and rising of bulk water temperature. It is also obvious that the existence of a coastline modi fies the general response feature of open ocean to tropical storms.
