Abstract: This paper demonstrates an isentropic representation of the Eliassen?Palm flux (EP flux) as a tool for diagnosis of the atmospheric zonal mean states. This is a full extension of the transformed Eulerian mean (TEM) to ...

Abstract: n analysis method is proposed for polar cold airmass streams from generation to disappearance. It designates a threshold potential temperature ?T at around the turning point of the extratropical direct (ETD) meridional ...
