本文对杭州湾地区十一个气象台站的地面气象资料作了对比分析,选取金山嘴(湾口北)、杭州(湾顶)、镇海(湾口南)三站作为代表站,对风,气温,降水,湿度,雾,台风等几个主要气象要素进行了统计分析,得到了杭州湾地区的一般气候特征。本区受季风影响,风向主要表现为季风特征,风速湾口大于湾顶。气温受海洋气流的调节,夏季湾口气温稍低于湾顶,而冬季呈现出高于湾顶的趋势。全年空气比较湿润,多雨,年降水量几乎都在1000.0毫米以上,主要集中在3—9月。
In this paper, the ground meteorological data of eleven meteorological stations in Hangzhou Bay are compared and analyzed. Three representative stations, Jinshanzui (Bayou North), Hangzhou (Bayou) and Zhenhai (Bayou South) , Humidity, fog, typhoon and other major meteorological elements were analyzed and the general climatic characteristics of Hangzhou Bay were obtained. Affected by the monsoon in this area, the wind direction is mainly characterized by the monsoon, and the wind speed is larger than the bay top. Temperatures were regulated by ocean currents, with the temperature in the mouth of the bay slightly lower than that of the bay in summer and a trend higher than that of the bay in winter. The air is humid and rainy all year round, and the annual precipitation is almost above 1000.0 mm, mainly in the period from March to September.
