Abstract: Based on mesoscale numerical forecast of high resolution and intensive observation data of automatic weather stations as well as numerical forecast explanative application technology in villages and towns weather forecast operational system of Liaoning province,precipitation forecast of villages and towns stations was developed by PP equations and analogue method.In addition,villages and towns weather forecast operational flow was established,and villages and towns weather forecast network was developed,which can realize the distribution,revision,save,report,scoring and management of villages and towns short-term meteorological element forecast product such as precipitation,the maximum air temperature and the minimum air temperature in next 24 h for 952 stations of Liaoning province.At the same time,the technological method and work flow of villages and towns weather forecast system were summarized.
