摘要
在分析长江口外海陆风速差的日变化、季节变化特征的基础上,考虑了海陆不同下垫面的粗糙度和温度层结对风速变化的影响,建立了一个利用沿海陆地站测风推算近岸海上风速的模式。计算结果表明,推算值与实测值有着相当好的吻合,具有一定的实用价值。
The characters were analysed of daily and seasonal variations of the land and sea breeze contrast off the Changjiang Estuary The effects of different surface roughness and temperature stratification between the iand and sen on the variation of wind speed were considered. Based on the results mentioned above, a model for estimating offshore wind speed from onshore meteorological measurements was established. The resuts show that the estimating values fit well with the observed data. The model is of some practical value.
