摘　　要：本文利用1986～1987年大亚湾海洋生态零点调查水文气象观测资料,分析讨论了大亚湾秋季水温层化消退过程。结果表明,该层化消退过程出现在初秋,历时短暂且伴随湾内水体热含量增加。该过程与秋季季风转换期粤东沿岸海洋动力调整及其和大亚湾的相互作用密切相关,外海暖水入侵和层化消退是河口和近海沿岸水相互作用的结果。This paper, by using hydrometeorological data from Marine Ecology Zero Point Survey of Daya Bay in 1986～1987, analyses and discusses the autumn process of temperature destratification in the Bay. We found that the destratification occurres in early autumn and the duration was short. It was also found that the process was associated with increasing marine heat content in the Daya Bay. Further computation of heat budget reveals a warm water intrusion from open ocean. The dynamic mechanism of the destratification is not clear yet, but the results exhibit clearly that it is closely associated with the dynamic adjustment of the coastal waters off eastern Guang Dong during the change of monsoon in autumn. It is suggested that the warm water intrusion and the distratification is caused by the interaction of the estuary with the adjunct coastal water.
