Abstract
Using general weather stations data in 2011 Qing county countries old station about temperature,relative humidity,wind,deep geothermal,statistical analysis,the results show that:Due to the old and new site surrounding environment different,nature of the underlying surface,observation data have certain differences.Month average temperature difference is-0.2-0.2 ℃,monthly average highest temperature difference is 0.4-0.4 ℃,monthly average minimum temperature difference is 0.4-0.0 ℃,extreme maximum temperature difference of -0.6-0.9 ℃,extreme minimum temperature difference of-1.9-0.9 ℃,annual average temperature,annual mean maximum temperature of old and new stations are all the same,annual mean minimum temperature was slightly lower than the old station.New station extreme maximum temperature higher than the old station,annual extreme lowest temperature it was significantly lower than the old station.Old station monthly average relative humidity difference of 1％-1％,minimum monthly relative humidity difference of-3 ％-3 ％,the minimum relative humidity in new station is higher than the old station.Old station in 2 minutes on average wind speed difference is 0.5-1.2 m/s,monthly maximum wind speed difference is 2.5-3.7 m/s,monthly maximum wind speed difference is 1.3-5.1 m/s,maximum wind speed,annual maximum wind speed new stations are larger than the old station.Years up to the new stations for SSW,old station for SW and wind direction frequency of new station is smaller than the old station.Old and new station in 40 centimeters geothermal month average difference of 1.3-1.9 ℃,and g0 cm geothermal month average difference of 1.2-1.2 ℃,and 160 cm geothermal month average difference of 2.0-2.0 ℃,and 320 cm ground temperature on the average difference was 0.5-0.8 ℃,the deep geothermal average annual temperature of new stations are higher than the old stand.关键词
