摘    要:利用二维数值模式,研究了在海雾过程中海温场、气温场、湿度场、风场等海洋气象条件的影响。结论如下:(1)海温主要影响海雾的生成过程,当海雾生成后,它的作用就逐步减小了;(2)气温梯度(暖平流)较大,不利于海雾生成,逆温不是海雾生成的一个充要条件;(3)相对湿度大小及其分布是海雾能否生成的物理基础;(4)风速大不利于海雾生成,但海雾一旦生成,则有利于其发展

关 键 词:海雾  数值模式  海洋气象条件影响

Abstract:Using a two dimensional model, the effects of air sea condions such as air temperature, humidity, wind and sea surface temprature on the process of seafog are studied. It is shown that (1) sea temperature has a great influence on the initial formation of seafog and a decreasing control after seafog formation; (2) a great gradient of air temperature and a reverse lapse of temperature is not of benifit and not absolutely necessary for the formation of seafog, respectively; (3) the magnitude and the distribution of relative humidity play a critical impotrant role on fog formation and development; (4) wind with higher speeds impedes the formation of seafog but promotes the development of seafog once it has formed.
Keywords:seafog  numerical model  the effects of air  sea conditions
