RISA Quasigeostrophic Model for Moist Storm Tracks
Publisher: American Meteorological Society
Abstract: he effect of moisture and latent heat release is investigated in the context of a three-level quasigeostrophic model on the sphere. The model is based on an existing dry model that was shown to be able to reproduce the ...
Surface Arctic Amplification Factors in CMIP5 Models: Land and Oceanic Surfaces and Seasonality
Publisher: American Meteorological Society
Abstract: rctic amplification (AA) is a major characteristic of observed global warming, yet the different mechanisms responsible for it and their quantification are still under investigation. In this study, the roles of different ...
Impact of Greenhouse Gas Concentration Changes on Surface Energetics in IPSL-CM4: Regional Warming Patterns, Land–Sea Warming Ratios, and Glacial–Interglacial Differences
Publisher: American Meteorological Society
Abstract: The temperature response to a greenhouse gas (GHG) concentration change is studied in an ocean?atmosphere coupled model?L?Institut Pierre-Simon Laplace Coupled Model, version 4 (IPSL-CM4)?for both a glacial and an interglacial ...
An Energetics Study of Wintertime Northern Hemisphere Storm Tracks under 4 × CO2 Conditions in Two Ocean–Atmosphere Coupled Models
Publisher: American Meteorological Society
Abstract: Different possible behaviors of winter Northern Hemisphere storm tracks under 4 ? CO2 forcing are considered by analyzing the response of two of the ocean?atmosphere coupled models that were run for the fourth Assessment ...
Links between Rossby Wave Breaking and the North Atlantic Oscillation–Arctic Oscillation in Present-Day and Last Glacial Maximum Climate Simulations
Publisher: American Meteorological Society
Abstract: Upper-tropospheric Rossby wave?breaking processes are examined in coupled ocean?atmosphere simulations of the Last Glacial Maximum (LGM) and of the modern era. LGM statistics of the Northern Hemisphere in winter, computed ...
