A ground observation station was established at the Yuanyang Lake Power Plant in Ningxia Province,and the temperature,wind direction,wind speed and 60-m gradient observation data were obtained.The synchronous observation for one year was also conducted at a nearby weather station(Lingwu Station).The comparison analysis reveals the climatic characteristics of the power plant.By means of the observed data from the Lingwu weather station from 1971 to 2000 and the correlative analysis method,the adjustment is made and the characteristics of the year-to-year meteorological elements at the power plant year after year are obtained.The results show that wind direction and velocity at the power plant are obviously different from those at the Lingwu weather station.The analysis results are mainly used in the installation and safe operation of the air-cooling system of local thermoelectric power stations.
