摘要
2006年4月11日～12日岚县境内出现了历年同期少见的强寒潮天气过程，并伴有暴雪，12日早晨最低气温达-10．6℃，是历年同期的最低值。本次过程降水量充足，彻底解除了前期连续35d无降水的旱情，改善了土壤墒情，对春耕、春播很有利，降低了森林火险等级。同时奇冷的天气致使正处于盛花期的仁用杏花全部冻落，给岚县造成了较重的经济损失。本文通过对天气形势、物理量，单站气象要素等方面的综合分析，探讨春季强寒潮天气影响山西时，环流演变和高低空的配置情况及单站要素的反映。
A strong cold wave weather process occurred in Apr 11 - 12 2008, accompanied by snowstorm and made min air temperature dropped to - 10. 6℃ which was the lowest value in the same period over the past years. The peculiar weather relieved continuous drought of 35d and reduced the grade of forest fire, but, the strong cold wave brought severe economic loss which made blooming apricot blossom freeze and fade. In this paper, the weather situation, physical quantity, meteorological elements of local station in this weather process are analyzed.
