通过对海州湾沿岸3座梯度测风塔和19座自动气象站一年的逐日24h自记风资料的统计,得到海州湾沿岸的海陆风,在此基础上提出了海陆风“净值”的概念.结合海陆风“净值”分析海州湾沿岸的海陆风环流特征发现:海州湾沿岸南北两段的海陆风具有明显的差异,南北走向的海岸海陆风比西北一东南走向海岸的弱,且转换时间迟；并粗略地估计了海风向陆地内的水平伸展宽度在45 km左右,夏季海风的垂直伸展高度可达625 m或以上.%Using the daily 24-h wind datasets, which are derived from 3 gradient anemometer towers and 19 automatic meteorological stations, we investigated the land-sea breeze in the coastwise area of Haizhou Bay and proposed the concept of net value of land-sea breeze. Combined with the net value analysis of land-sea breeze circulation in the coast, it was demonstrated that the land-sea breeze in the south and north coasts exhibited significant differences: the land-sea breeze in the north-south coast was weaker than that in the northwest-southeast coast, and it had a later conversion time. The horizontal extension of sea-breeze towards land area was about 45 km. In summer, the vertical extension height could reach 625 m or above.
