Abstract Using observational data from intelligent and automatic weather stations of Nanchang Ai Xi lake wetland park test base from October to November 2014,each meteorological element is analyzed and the reasons for differences between two stations are discussed. The results show that although there are some differences between observational datas of two measurement modes,in which the maximum average surface wind direction and speed,the average maximum temperature of the ground and the average minimum surface humidity have large different,they are still within the allowable range of accuracy. In addition to the difference caused by instrument performance and operational principle,the changes of observation environment and special weather phenomenon are also important reasons for the difference.
