Analysis on a Weather Process of Cold Wave, Heavy Snowstorm in Altay and Ili Regions
Abstract: Based on the data of conventional upper and field and numerical forecast products of T639, a cold waves and snow storms weather happened from 15 to 20 January 2010 in Altay and Ili Regions, which is comprehensively inves-tigated. The results show that the ridge of the Black sea developed and moved to east with ridge of European, and the Northeast wind formed and strengthen in front of the ridge, then the trough moved to southward and westward. The northeast cold air in Taimyr Peninsula of the ridge was guided along the northeast air flow of ridge to the Siberia trough, which caused baroclinicity enhanced and forced the trough strongly developed and collapsed to southeast. The Euro-pean ridge collapsed to southeast too, which forced the cold air broke out southward in west Siberia and caused strong cold wave and heavy snowstorm in northern Xinjiang. A comparative analysis of forms field, surface filed and physical elements is made, which provided some reference for weather forecast in Xinjiang.
