Analysis on the Relationship between the Occurrence of Red Tide and Synoptic Situation in Yangtze River Estuary

赤潮发生是极其复杂的多种因素相互作用的结果.长江口海域历来是赤潮高发区,根据2000—2013年长江口海域赤潮事件和气象水文观测数据资料,对赤潮发生与天气形势演变的关联性进行分析,初步探讨了该海域赤潮发生过程中天气形势的演变特征和变化规律.

The occurrence of red tide is extremely complex, which is considered as the comprehen- sive results of various factors. The Yangtze River estuary area has always been a high incidence of red tide. In this paper, according to the events of red tide and meteorologic and hydrologic data in Yangtze River estuary from 2000 to 2013, the relationship between the occurrence of red tide and the synoptic situation was analyzed, and the evolution characteristics as well as regular pat terns of synoptic situation in the process of red tide were also discussed.
