The Influence of Relocation of Changji Station on Temperature, Air-pressure and Precipitation

ZHOU Hao-nan,CHEN Xiao-yan,WANG Qiu-xiang(Xinjiang Meteorological Information Centre,Urumqi 830002,China)  
This paper chose 366 comparative observation values of temperature,air-pressure and precipitation(214 of them)from the new and old station of changji in 2008,and tested variance and average value of daily data observed in the two station with F and U test,we found that: the significance level of minimum,maximum and mean air pressure and the minimum air temperature are all at α=0.05,to be significant differences in average value before and after relocation,and there are significant differences of all elements in variance except precipitation at α=0.05 level.After data series standardizing and contrasting,we detected that the air-pressure standardization curve is superposition mainly,but the temperature series is variety considerably,especially the minimum temperature.Seen from accumulative anomaly results,the variation trend is same mainly in the two stations,but variation float of data series in the new station is more than the old.
