摘　　要：根据福建沿海2001～2008年赤潮灾害资料以及相应时期的气象数据,寻找与赤潮灾害发生密切相关的气象因子,分析赤潮灾害发生期间的地面及不同高度的天气形势,并探讨南方涛动指数与赤潮灾害发生的关系,在此基础上根据前期气温、风、云及海况进行福建沿海赤潮灾害气象预报。研究结果表明,福建沿海的风、气温、湿度、日照和气压等气象因子与赤潮的发生存在着密切的关系,但不同海区影响赤潮发生的主要气象因子不尽相同,低层850 hPa和地面形势能较好地反映福建沿海赤潮发生的天气背景,南方涛动指数与第2年赤潮发生日数有着很好的对应关系,二者相关系数为-0.745。The relationship between red tide disasters in the coastal area of Fujian Province and meteorological conditions is studied,and the circulation patterns for forecasting red tide disasters meteorologically is summed up.The red tide disaster data from 2001 to 2008 in the coastal area of Fujian Province and meteorological data of the corresponding period are used to seek the meteorological factors correlated with red tide disasters,so to analyze meteorological situations on the surface and at different levels during red tide disasters and to study the relationship between Southern Oscillation Index and occurrence of red tide disasters.Results show that meteorological factors such as wind,temperature,humidity,sunshine,and pressure in the coast area of Fujian are correlated well with red tide disasters,but the major factors vary in the different sea areas.The circulation situation at 850 hPa and on surface can better reflect the meteorological background during red tide disasters.Results also show good corresponding relation,with the correlation coefficient being-0.745,between Southern Oscillation index and the occurrence days of red tides next year.
