An Interpretation of Sudden Warmings In Terms of Potential vorticity

摘要: Abstract A simple and concise interpretation of stratospheric sudden warmings is offered in terms Of the transient changes potential vorticity pattern. The warming viewed as a manifestation reversal mean (zonally averaged) relative distribution over deep layer stratosphere mesosphere. reversals zonal flow latitudinal gradient temperature are regarded merely accompanying features phenomenon. linchpin our particularly derived relationship between wave quasi-geostrophic flow. This points to possibility inducing by purely forcing tropospheric Furthermore, it indicates that duration amplitude wave-forcing, together with transmission properties zo...
