In order to develop and utilize the wind energy resource efficiently, and realize the target of stepping from a big wind energy country into a strong wind energy country, this paper summarizes the application status, problems and impacts on project benefits in various aspects of meteorological technology application in wind energy exploiting based on a large number of past projects practice, data analysis and test results. Furthermore, based on the analysis of atmospheric science principles and the special needs of wind power to meteorological technology, it is pointed out the key technical issues and direction should be noted in the applying process of wind energy assessment, numerical simulation and numerical prediction technology.
