中文摘要: 考虑了大气中凝结潜热作用,提出湿Q矢量概念并推导出非地转的湿Q矢量表达式以及用湿Q矢量散度作强迫项的ω方程。利用常规气象资料作实例分析,结果表明在低纬度地区湿Q矢量分析优于准地转Q矢量分析。

Abstract:Taking acount of the latent heat of the vapour condensation in the atmosphere,the concept of the wet Q vector was proposed. An expression of the wet Q vector and the non geostrophic ω equation,in which the divergence of wet Q vector was taken as a forcing term,was derived. By using routine meteorological data for diagnostric analysis,the results show that the wet Q vector is better than the quasi geostrophic Q vector in the low latitude area.
