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。
中文关键词: 湿Ｑ矢量，准地转Ｑ矢量，凝结潜热
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.
