Preliminary analysis of the summer and winter meteorological conditions in Altun Mountain National Nature Reserve

根据阿尔金山国家级自然保护区自动气象站冬、夏季数据资料,对该区冬、夏气象状况的特点进行了分析.结果表明:阿尔金山国家级自然保护区是新疆中部气温低值中心之一,冬季平均气温-14.0℃左右,夏季平均气温9.0℃左右.日温差大,冬季日较差平均值为16.0℃,夏季为12.0℃.夏季多风,日平均瞬时风速3.6 m·s-1,高于冬季日平均瞬时风速2.4 m·s-1;年降水量可达300 mm,主要集中在夏季,表现为雨暖同期.

According to the meteorological data recorded by an automatic meteorological station in Altun Mountain National Nature Reserve, the characteristics of summer and winter meteorological conditions are analyzed. It is found that the Altun Mountain National Nature Reserve is one low-temperature center in the central Xinjiang. The air temperature averaged in winter is - 14.0 ℃, about 10.0 ℃ lower than that in Hotan and 6 -8 ℃ lower than that in the similar latitude areas such as Yining and Hami. The mean air temperature in summer is 9.0 ℃, 15 ℃ lower than that in surrounding areas generally. Instantaneous wind speed averaged in summer is 3.6 m s^-1 , higher than that in the winter, 2.4 m s^-1 Precipitation is high to 300 mm a^-1 , mainly concentrated in summer, showing a characteristic of warm-rain over the same period.
