Analysis of the Meteorological Element Variations before and after the Relocation of Hukou National Station
摘要
Abstract
Using observation data from the old and new stations of the Hukou National Basic Meteorological Station before and after its relocation,along with Digital Elevation Model(DEM),and GlobeLand30 land cover classification data,the study analyzes the differences in meteorological elements before and after the relocation and the causes that lead to the differences using statistical methods such as difference analysis.The results show that the pressure difference is relatively small,with a difference of 0.6 hPa.The new station's monthly average temperature and monthly minimum temperature are higher than the old station,with differences ranging from 0.3 to 7.5℃.The monthly maximum temperature is higher at the new station in May,October and November,but lower in the remaining months.The highest precipitation at the new station occurs in July,while in the old station,it's in June.The new station generally records fewer sunshine hours than the old station,except in April,in which it exceeds the old station by 7.6 hours.The monthly average relative humidity at the new station is 0.5%～4.2%higher than that at the old station in January,February and from May to August.The monthly minimum relative humidity at the new station is generally higher than that at the old station.The wind speed at the new station is significantly higher than that at the old station,with minor changes in wind direction.The most frequent wind direction at the new station is NNE,while it is NE at the old station.The main reasons for the differences in meteorological elements are attributed to variations in altitude,terrain,and underlying surface conditions of the two stations,as well as differences in the surrounding detection environment between the two station sties.关键词
