| 摘 要： | 利用2011年青县国家一般气象站新旧站的气温、相对湿度、风、深层地温等资料,对青县气象站迁站观测资料进行统计对比分析。结果表明,由于新旧站址周围环境不同、下垫面性质不同,造成观测数据有一定差异。新旧站月平均气温差值为-0.2～0.2℃,月平均最高气温差值为-0.4～0.4℃,月平均最低气温差值为-0.4～0℃,月极端最高气温差值为-0.6～0.9℃,月极端最低气温差值为-1.9～0.9℃,年平均气温、年平均最高气温新旧站均相同,年平均最低气温新站略低于旧站;年极端最高气温新站高于旧站,年极端最低气温新站明显低于旧站。新旧站月平均相对湿度差值为-1%～5%,月最小相对湿度差值为-3%～3%,年最小相对湿度新站高于旧站。新旧站月2 min平均风速差值为0.5～1.2 m/s,月最大风速差值为2.5～3.7 m/s,月极大风速差值为1.3～5.1 m/s,年最大风速、年极大风速新站均比旧站偏大;年最多风向新站为SSW,而旧站为SW且年风向频率新站小于旧站。新旧站40 cm地温月平均差值为-1.3～1.9℃,80 cm地温月平均差值为-1.2～1.9℃,160 cm地温月平均差值为-2.0～1.8℃,320 cm地温月平均差值为-0.5～0.8℃,各深层地温年平均温度新站均高于旧站。

| Abstract: | Using general weather stations data in 2011 Qing county countries old station about temperature, relative humidity, wind, deep ge- othermal, 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 tempera- ture 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 tempera- ture 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 rela- tive 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, month- ly 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, an- num 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 di- rection 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 80 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 sta- tions are higher than the old stand. |
