摘　　要：以 1 998年 7～ 1 0月辽东湾海域赤潮为例 ,分析了气象因素对赤潮全过程的影响。分析表明 :气温、降水、光照、风速等气象因素与赤潮的发生、发展和消亡有密切的关系 ,气象条件是诱发赤潮的关键因素。在温度适宜的情况下 ,降水量的多少对赤潮的发生、发展有关键的作用。最后探讨了利用气象因素与赤潮的关系进行赤潮发生。Based on the example of red tide happened in Liaodong Gulf from August to October in 1998,the effects of meteorological factors on the whole process of the red tide are analyzed.The results show that meteorological factors,which are the key factors in inducing red tide such as temperature,precipitation,sunlight,wind etc.are close related to its happening,developing and dying down.There are large amount precipitation over land before it,obvious increase of temperature when it begins,clear sky,higher temperature,lower wind speed during its developing time,and temperature decrease or precipitation when it will die down.At fit temperature,precipitation play an important role of its happening and developing.At last,elementary idea of meteorological potential prediction of red tide is discussed based on the relationship between meteorological factors and red tide.
