Analysis on a Cold Wave Weather Process in Winter in Gansu
摘要
Abstract
[ Objective ] The research aimed to analyze a cold wave weather process in winter in Gansu, [ Method ] Based on routine observa-tion data and numerical forecast products, formation reason and physical quantity characteristics of a cold wave process during 2 - 5 Decem-ber, 2008 were comprehensively analyzed by synoptic analysis and diagnostic analysis methods. [ Result] The cold wave weather belonged to "translot turning vertical type". Collapse of the Urals ridge, turning vertical of the translot and strengthening south of the 8round cold high in-duced the cold wave. Development of the Siberian low vortex drove the small branch of the polar cold air supplement south, playing certain promoting role in outbreak of the cold wave. Physical quantifies in the cold wave process also had very good expression, such as vurticity, tem-perature advection, etc. [Conclusion] This research had important indication effect for early warning, forecast and decision service of the fu-ture similar weather process.关键词
