Understanding the Changes of Stratospheric Water Vapor in Coupled Chemistry–Climate Model Simulations
Publisher: American Meteorological Society
Abstract: Past and future climate simulations from the Goddard Earth Observing System Chemistry?Climate Model (GEOS CCM), with specified boundary conditions for sea surface temperature, sea ice, and trace gas emissions, have been ...
The Downward Influence of Sudden Stratospheric Warmings: Association with Tropospheric Precursors
Publisher: American Meteorological Society
Abstract: Tropospheric features preceding sudden stratospheric warming events (SSWs) are identified using a large compendium of events obtained from a chemistry?climate model. In agreement with recent observational studies, it is ...
Connections between the Spring Breakup of the Southern Hemisphere Polar Vortex, Stationary Waves, and Air–Sea Roughness
Publisher: American Meteorological Society
Abstract: robust connection between the drag on surface-layer winds and the stratospheric circulation is demonstrated in NASA's Goddard Earth Observing System Chemistry?Climate Model (GEOSCCM). Specifically, an updated parameterization ...
Airmass Origin in the Arctic. Part I: Seasonality
Publisher: American Meteorological Society
Abstract: he first climatology of airmass origin in the Arctic is presented in terms of rigorously defined airmass fractions that partition air according to where it last contacted the planetary boundary layer (PBL). Results from a ...
Air-mass Origin in the Arctic. Part II: Response to Increases in Greenhouse Gases
Publisher: American Meteorological Society
Abstract: uture changes in transport from Northern Hemisphere (NH) midlatitudes into the Arctic are examined using rigorously defined air-mass fractions that partition air in the Arctic according to where it last had contact with ...
