辽东半岛南部海陆风分析

辽东半岛南部位于亚洲东岸的季风区内。季风气压场、西风带下层移动性高低压系统、局地性海陆因子对气压场性质的日周期调整是影响该地风向的基本因子。本文引用分别位于东西岸的皮口和新金站1985年夏季连续风向资料,分析了各因子的影响与风频分布之间的关系、各因子对不同方向风频做出的贡献、确立了海陆风存在的事实。并在此基础上,分析了两岸海陆风的特点、规律和差异。

The Analysis of Land and Sea Breezes on South Liaodong Peninsula

The southern part of the Liaodong peninsula is located in the area of temperate monsoon of the East Asia.The wind directions in this region are mainly controlled by the seasonal variatiations of the monsoon,the moving low and high pressure systems in the lower layer of the westerlies,and the regional factors such as the location to tne sea.Using the data on summer wiad directions of pikou station on the east coast and Xinjin station on the west coast,the author has analyzed the correlation of the wind frequencies with the factors mentioned adove,and checked the contributions of each factor to different wind frequencies.It has been found that the land and sea breezes do exist along both sides of the peninsula.The feature,regularity and difference of the breezes on the west and east coasts are also discussed.
