| 摘 要： | 塔克拉玛干沙漠近几年来沙尘暴发生频率增加,强度增大,为了研究不同尺度沙尘暴的规律,利用2005-2014年塔克拉玛干沙漠腹地塔中及周边14个气象台站沙尘暴资料,给出塔克拉玛干沙漠腹地塔中区域性与局地性沙尘暴天气过程的定义,从区域性与局地性沙尘暴持续时间,能见度,类型,时间变化等特征进行分析。研究结果表明：(1)10塔中发生沙尘暴170d比沙漠南缘和北缘高,比肖塘少,其中区域性沙尘暴80d,局地性沙尘暴90d,天气过程区域性64次,局地性80次；(2)塔中区域性沙尘暴不论是持续时间还是能见度总体上比局地性沙尘暴持续时间长,能见度低；(3)区域与局地沙尘暴可以按主导风向分为5类,但各类沙尘暴在区域性与局地性沙尘暴中表现出季节分布；(4)区域性与局地性沙尘暴10a波动增长,区域性沙尘暴多发生在春季,局地性沙尘暴多发生在夏季,区域性沙尘暴年际和年内变差系数都小于局地沙尘暴,一日中区域性与沙尘暴白天多于夜晚。

| Abstract: | : Recently the sandstorm in Taklimakan Desert happened more frequently and heavily. In order to study the law of the sandstorm from different scale, we will give the definition of weather process in the view of its local and regional sandstorm and analyze its duration, visibility, types and temporal variation from local and regional sandstorm by the sandstorm documents of 14 meteorological logical stations Tazhong and around Taklimakan Desert from 2005 to 2014. The results show that: (1) The sandstorm oftazhong lasts 170 days, and is higher than south fringe and north fringe of desert, but is less than Xiaotang, including: local sandstorm is 80 days, regional sandstorm is 90 days, the local weather process is 64 times, local one is 80 times; (2) The local sandstorm possesses longer duration and a lower visibility than regional sandstorm totally; (3) We can divide the local and regional sandstorm into 5 types according to the dominant wind direction and each kind of sandstorm embodies the seasonal distribution; (4) The two kinds of sandstorm will increase within 10 years. The local sandstorm happens in the spring, while regional sandstorm in summer. The variation coefficient of local sandstorm is less than the regional sandstorm annual and within years. And the day during regional and localsandstorm is more than its night. |
