Description
Abstract:
Transport of potential vorticity and Eliassen-Palm fluxes. Analysis and diagnostic of PV data from the stratosphere and upper troposphere. Applying the divergence of the Eliassen-Palm-Vector to mid- and long-term forecasts and together with seasonal variations of eddy fluxes of PV, heat and momentum in the stratosphere/ upper troposphere estimation and prognosis of sub-seasonal trends. All in context with SST-anomalies, ENSO, QBO, Brewer-Dobson-Circulation and other diabatic factors.
