湄洲湾海雾的初步分析

分析福建湄洲湾1985－1992年海雾的气候特点，发现79％的海雾发生在2－5月。应用中国气象局北京气象中心出版的历史天气图，对本区海雾进行天气学分型，结果表明，有89％的海雾出现在锋面偏北，南高北低，东脊型中，利用850hPa天气型的消空条件，结合气象因子和单站资料，得出了湄洲湾海雾的短期预报指标，并建立了预报方程。

A preliminary analysis of maritime fog in Meizhou Bay

The climate features of maritime fog in Meizhou Bay from 1985 to 1992 are analysed. The maritime fog mostly (79%) occurs in the period from Feb. to May. By using the histor- ical weather maps published by Beijing Meteorological Center,the synoptic meteorology clas- sification is conducted for the maritime fog. The results show that 89% of maritime fog ap- pears between fronts northly,south-high and north-low,east-ridges of the weather patterns. By using high-ressure condition of 850hPa weather pattern and combining meteorological fac tors and data form a synoptic station,the indexes of short-range prediction and prediction e- quations are obtained for maritime fog in Meizhou Bay.
