摘要讨论了行星波作用通量Eliassen-Palm flux(E-P通量)在球面准地转条件下的表达式,纬圈环状总质量权重的变换形式,及其在绘图分析中的应用与技巧。结合实例,通过对欧洲中心再分析资料Interim的计算绘图,说明不同形式E-P通量在实际分析时的差异及特点。 The expression of Eliassen-Palm flux （E-P flux） in quasi-geostrophic spherical coordinates and its transformation form weighted by zonal annular total mass,involving its application and skills in graphic analysis,are discussed.Combined some plotting examples with Interim/ECMWF Re-Analysis （ERA-Interim） data,the distinctions and characteristics lying in real cases under different forms of E-P flux are illustrated.
