RISAssimilation of Stratospheric Temperature and Ozone with an Ensemble Kalman Filter in a Chemistry–Climate Model
Publisher: American Meteorological Society
Abstract: new stratospheric chemical?dynamical data assimilation system was developed, based upon an ensemble Kalman filter coupled with a Chemistry?Climate Model [i.e., the intermediate-complexity general circulation model Fast ...
Sensitivity of the Stratospheric Circulation to the Latitude of Thermal Surface Forcing
Publisher: American Meteorological Society
Abstract: sing the chemistry climate model Intermediate General Circulation Model?Fast Stratospheric Ozone Chemistry (IGCM-FASTOC), the authors analyze the response in the Northern Hemisphere winter stratosphere to idealized thermal ...
Stratosphere–Troposphere Exchange and Its Relation to Potential Vorticity Streamers and Cutoffs near the Extratropical Tropopause
Publisher: American Meteorological Society
Abstract: Two distinct dynamical processes near the dynamical tropopause (2-PVU surface) and their relation are discussed in this study: stratosphere?troposphere exchange (STE) and the formation of distinct potential vorticity (PV) ...
A New Perspective of Stratosphere–Troposphere Exchange
Publisher: American Meteorological Society
Abstract: Stratosphere?troposphere exchange (STE) is important for the chemical composition of both the stratosphere and troposphere. Modifications of STE in a changing climate may affect stratospheric ozone depletion and the oxidizing ...
