摘要
利用常规高空、地面观测资料和数值预报产品对2010年1月18-22日影响博州地区的一次强寒潮天气过程进行分析。结果表明:大风、强降温是本次寒潮天气的主要特征,造成大风和强降温的主要原因是前期气温异常偏暖,地面增压迅猛剧烈,阿拉山口风口的狭管效应对山口的大风也有增幅作用。
Using the conventional upper air,the surface observation material and the numerical forecasting productaffects the Bozhou area to January 18~22,2010 a strong cold wave process to carry on the analysis.The resultindicated:The gale,the strong temperature decrease are this cold wave chief features,creates the gale and thestrong temperature decrease primary cause is the preliminary temperature is exceptionally warm,ground turbo-charged swift and violent fierce,the Alashankou gusty area's slender tube effect also has the increased rangefunction to mountain pass's gale.
