摘　　要：本文利用2022、2023年1~12月安顺国家基本气象站迁站后新、旧站观测资料进行对比分析,表明观测站迁站造成了观测数据的差异,新站的平均气温、最高气温、最低气温、本站气压均低于旧站,相对湿度、2 min平均风速、大雾天气日数均大于旧站。海拔高度差、环境差异、地形差异以及城市热岛效应是造成气象要素差异的重要原因,新旧站气象要素的差异为新旧资料的使用提供一定的订正依据。In this paper, the observation data of Anshun National Basic Meteorological Station after its relocation from January to December in 2022 and 2023 are compared and analyzed. The results show that the difference of observation data is caused by the relocation of the observation station. The average temperature, maximum temperature, minimum temperature and air pressure of the new station are all lower than those of the old station, while the relative humidity, 2 min average wind speed and number of fog-weather days of the new station are all greater than those of the old station. Altitude difference, environmental difference, terrain difference and urban heat island effect are important reasons for the difference of meteorological elements, and the difference of meteorological elements between new and old stations provides a basis for the use of new and old data.
