摘要 准地转运动的 Eliassen-Palm 通量的欧拉形式被推广到包括凝结加热的大规模涡流强迫。仅需要修改通量的垂直分量；它增加了。埃利亚森-帕尔姆定理仍然成立，但不是假设非绝热加热为零，而是假设排除与大规模运动相关的凝结的非绝热加热为零。只要添加欧拉纬向平均湿度场静止的假设，非加速定理也仍然成立。概括保留了驻波能量通量与 Eliassen-Palm 通量之间的关系，但现在自动包含了波凝聚效应。此外，概括得出描述湿度场的总涡流强迫的函数。广义埃利亚森-帕尔姆通量的散度是根据大气观测计算出来的，并与标准通量的散度进行比较。电子...
Abstract The Eulerian form of the Eliassen-Palm flux for quasi-geostrophic motion is generalized to include large-scale eddy forcing of condensation heating. Only the vertical component of the flux has to be modified; it is increased. The Eliassen-Palm theorem still holds, but instead of assuming that the diabatic heating is zero, one assumes that the diabatic heating excluding condensation associated with the large-scale motions is zero. The non-acceleration theorem also still holds, provided one adds the assumption that the Eulerian zonal mean moisture field is stationary. The generalization preserves the relationship between stationary wave energy flux and the Eliassen-Palm flux, but now wave condensation effects are automatically included. In addition, the generalization leads to a function describing the total eddy forcing of the moisture field. The divergence of the generalized Eliassen-Palm flux is calculated from atmospheric observations and compared with the divergence of the standard flux. The e...
