Comparison of conventional and transformed in the troposphere
Abstract
The effect of synoptic‐scale transient eddies on the mean zonal current in the troposphere and lower stratosphere is examined using conventional and transformed Eulerian diagnostics. In each case the partial solution of the Eliassen‐Kuo diagnostic equation for the meridional circulation is obtained using as forcing functions only transient eddy (TE) fluxes of heat and momentum. This solution is then used to calculate the Coriolis force and the advective terms in the zonal mean momentum equation. the ‘transient‐eddy‐induced’ zonal momentum tendency is defined as the sum of these terms and the eddy flux terms in the zonal momentum equation. Although conventional and transformed Eulerian diagnostics give the same transient‐eddy‐induced momentum and kinetic energy tendencies, the interpretation of the mechanisms involved is different.
