【摘要】 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.更多还原

【Abstract】 According to the meteorological data recorded by an automatic meteorological station in Altun M ountain National Nature Reserve,the characteristics of summer and winter meteorological conditions are analyzed. It is found that the Altun M ountain 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.更多还原
