湿Q矢量在一次冷锋降雪过程中的应用

Analysis By Diagnosis of Wet Q Vector of a Heavy Snowfall

摘要: 利用常规气象观测资料和NCEP 1°×1°再分析格点资料,对2008年1月28—29日一次强降雪天气过程进行诊断分析,计算了非地转湿Q矢量流场、非地转湿Q矢量水平和垂直分布以及非地转湿Q矢量锋生函数。结果表明,非地转湿Q矢量辐合区是强

Abstract: A heavy snow process during January 28 to 29,2008 is diagnosed by studying the ageostrophic wet Q vector stream field,horizontal and vertical distribution of the ageostrophic wet Q vector and the ageostrophic wet
