摘要
以杭州湾沿岸１９个测站１９８２年１，７两个月风的自记记录为依据，对杭州湾沿岸海陆风环流进行了研究，得到了若干特征：（１）海风强而维持时间短；陆风弱而维持时间长。（２）海陆风相互转换的时间在海岸线附近最早。门）海陆风向内陆伸展的范围一般在５０ｋｍ左右。（４）陆风（海风）盛行时，在桐庐、绍兴、杭州湾中部和舟山群岛南部一带，存在一条辐合（辐散）线，主要辐合（辐散）中心也都在这一带。（５）杭州湾北岸海陆风比南岸弱。（６）海陆风相互转换时间北岸均比南岸迟６～８个小时。（７）南北两岸海陆风维持时间不同。
In this paper,the autographic records of wind from 19 meteorological Stations at the coast of HangZhou Bay in January and July 1982 are used to calculate and analyse in detail the circulation and divergence field of sea-land breeze over the coast of HangZhou Bay.By analysing the characteristics of sea-land breeze circulation over the coast of Hangzhou Bay,the author find that:(1)The sea breeze is stronger than the land breeze,but its maintenance bine is shorter than that of the latter.(2)The transition from the sea breeze to the land breeze and vice versa over the coast of Hangzhou Bay is earlier than that over other regions.(3)The horizontal dilatation extension of sealand breeze toward inland is about 50km.(4)When the land breeze prevails,there is a convergent line along Tonglu,Shaoxing,the middle region of Hangzhou Bay and the South of Zhoushan Islands.The main convergent centres are just situated on the same regions. However,during the prevailing sea breeze period, there is a divergent line along the above regions.The main divergent centres are just situated on the same regions.(5)The strength of sea-land breeze over northern coast of Hangzhou Bay is weaker than that over southern coast of Hangzhou Bay. (6)The transition time from the sea breeze to the land breeze and vice versa over northern coast of Hangzhou Bay is 6～8hours later than that over southern coast of Hangzhou Bay.(7)The maintenance bine of sea-land breeze over northern coast of Hangzhou Bay is differ from that over southern coast of Hangzhou Bay.
