ResumoSimultaneous observations of wind speeds onshore and offshore have been analyzed.The data (1989.5-12) show that the rates of the wind speeds offshore to those onshore are not always over 1.Analysis indicates that the rate is a function of some factors, such as the roughness of the land station,the atmospheric stability,the station distance from the coastline and the wind speed over the sea. The observed facts have been explained theoretically饰using the theories and experimental results on the boundary layer meteorology, also some regular characteristics of herate are presented.
