Climate characteristics of sandstorm of strong wind area in Xinjiang
摘要
Abstract
Based on the sandstorm days data from seven weather stations of strong wind area in Xinjiang, the climate variation features of the sandstorm in Sanshili Wind Area, Baili Wind Area and the surrounding area in Xinjiang are analyzed in this paper. It is showed as follows: (1) Benefiting from the advantageous topographic condition, the systematic weather process in the researching regions, especially the typical gale area, used to form extremely strong downslope wind and narrow-pipe wind with features of high intensity and long duration, which provide sufficient dynamic conditions for the generation and development of sandstorm. (2)The 1950s and 1960s are the high occurrence rate period for the referred gale region in Xinjiang. Meanwhile, affected by terrain condition, the frequency of sandstorms over typical gale region in Xinjiang is lower than that in other abundant sand and dust source zone, the occurrence rate of which showed a decreasing tendency with time, with a slight higher frequency in Baili Wind Area than that in Sanshili Wind Area. ( 3 ) With the influence of sytematic weather process, topography and landsurface conditions, the seasonal distribution of sandstorms observed at different observatory in the gale region in Xinjiang showed distinct disciplines, which is mainly characterized by double peak in spring and summer, single peak in spring and single peak in summer respectively.关键词
