| 摘 要： | 利用2016-2018年库尔勒气象站迁站前后基本气象要素的观测资料进行对比分析,结果显示：(1)平均气温、平均最低气温年、月值均是新站低于旧站,年值分别低2.1℃和4.1℃,年平均最高气温持平；春季气温差值变化相对较小,夏、秋、冬季气温差值变化相对偏大。(2)各月相对湿度新站大于旧站,各季相对湿度差值夏季最大,年平均相对湿度新站比旧站高11%。(3)平均气压新站高于旧站,年平均气压差值为3.2pha。各季差值冬季最大,(4)平均风速新站比旧站偏大0.1m/s,春季、夏季风速大于其他季节；最大风速新站比旧站偏大1.3-6.2m/s；主导风向由ENE转为E。(5)年平均气温、最低气温、平均湿度和年平均气压,迁站前后资料有显著差异,年平均最高气温、平均风速无显著差异。(6)测站周围环境、海拔高度、下垫面、地形等因素是造成新旧站气象要素差异的主要原因。

| Abstract: | Using the observation data of basic meteorological elements before and after the relocation of Korla weather station in 2016-2018, the results show that: (1) average temperature, average minimum temperature, annual and monthly values are lower than the old station, the annual value The annual average maximum temperature is flat at 2.1 °C and 4.1 °C, respectively; the temperature difference in spring is relatively small, and the temperature difference in summer, autumn and winter is relatively large. (2) The average relative humidity of each month is greater than that of the old station. The average relative humidity of each season is the largest in summer, and the new annual average relative humidity is 11% higher than the old station. (3) The average pressure new station is higher than the old station, and the annual average air pressure difference is 3.2hpa. The seasonal difference is the largest in winter, (4) the average new wind speed station is 0.1m/s larger than the old station, and the spring and summer wind speed is higher than other seasons; the new wind speed new station is 1.3-6.2m/s larger than the old station; dominant wind direction Change from ENE to E. (5) The surrounding environment, altitude, underlying surface, topography and other factors are the main reasons for the differences in meteorological elements. (6) There is no significant difference in meteorological elements between the old and new stations, and the values can be used continuously. |
