The wind speed correction method at different height for weather stations in ZhouShan
摘要
Abstract
In order to effectively utilize the wind speed data of the coastal stations in Zhoushan, remove the error of wind speed caused by height difference, and make the wind speed data of each site more representative, comparable, and applicable, we unified the wind speed data of each site to the same height. To analyze years of wind data at each weather station in Zhoushan, we used exponential model to describe wind profile and least squares method for data fitting. The results showed that underlying surface, wind speed and atmospheric stratification status were closely related to wind changes in different heights. Different underlying surface had different shear coefficient. The larger the wind speed was, the smaller the surface friction would be; the weaker the ability to change the wind speed, the smaller the shear coefficient. Due to the stratification changed in a day, shear coefficient changes existed, the maximum appeared at noon and the minimum appeared in the early morning.关键词
