Abstract: Based on the monthly meteorological data from new and old stations in Lushi in 2014, we calculated the average difference and standard deviation of annual difference of air temperature, maximum temperature, minimum temperature, relative humidity and 2 min average wind speed, respectively, by using the common difference statistical method; and calculated the consistency of wind direction by the coincidence rate. Through the above calculation results, we analyzed the meteorological data of the new and old station in Lushi and the causes of changes, in order to provide reference for the forecast service after station migration. The results showed that: the annual mean temperature and annual maximum temperature of the new station was 0.3℃ and 1.1℃ lower than those of the old station, respectively; and the annual minimum temperature was 0.1℃ higher than that of the old station; the difference of annual average relative humidity was 0 showing the relative humidity was less affected by the station migration; the wind speed of the new station was larger than that of the old, the annual average wind speed was larger than 1.0 m/s; the annual wind direction coincidence rate between the old and the new station was only 26%, and the consistency of wind direction between the two stations was very poor. This study provides references for the accurate forecast of meteorological elements in meteorological forecast service and the accurate utilization of meteorological data in scientific research and provides a basis for the continuation and homogenization of the meteorological data sequence of Lushi station.
