天山北坡不同海拔气候变化规律研究

A study of climate change regularity of different elevations of the northern slope of Tianshan Mountain

  • 摘要: 基于天山北坡不同海拔高度4个典型气象站56 a的气象数据,通过数理统计方法,分析和讨论了天山北坡垂直气候变化趋势和特征,研究该区域气候变化响应的垂直分异过程. 结果表明:①天山北坡气温总体呈上升趋势,海拔高度越高气温增长越明显. 高海拔区域全年增温,低海拔区域冬季增温最明显. 1984年天山北坡各站点同时出现温度低值. ②天山北坡降水总体呈上升趋势. 低海拔降水增量大,随着海拔的增加,增湿的趋势略有减少,且冬季降水量增加明显. ③随着时间和海拔变化,气候突变差异明显.

     

    Abstract: Based on the meteorological data of four typical weather stations in 56 years, the vertical climate change trend and characteristics of the northern slope of Tianshan Mountain were analyzed and discussed with the help of mathematical statistics, so as to find out the vertical differentiation processes of climate change response in this region. The main results are as follows: ① The temperature of the northern slope of Tianshan Mountain showed an upward trend: the higher the altitude, the more obviously the temperature increased. While temperatures increased all year round in the high altitude area, winter warming was most obvious in the lower elevations. And 1984 witnessed the lowest temperature on the northern slope of Tianshan Mountain. ② The precipitation showed an upward trend there. The precipitation increase was greater in the lower altitude area. And with the increase of altitudes, the trend of humidification increase would decline slightly. Moreover, the precipitation in winter increased obviously. ③ Abrupt climate change was obvious with the change of seasons and altitudes.
