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 ...
On the Reduced North Atlantic Storminess during the Last Glacial Period: The Role of Topography in Shaping Synoptic Eddies
Publisher: American Meteorological Society
Abstract: AbstractThe North Atlantic storminess of Last Glacial Maximum (LGM) fully coupled climate simulations is generally less intense than that of their preindustrial (PI) counterparts, despite having stronger baroclinicity. An ...
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 ...
Impact of Freshwater Release in the North Atlantic under Different Climate Conditions in an OAGCM
Publisher: American Meteorological Society
Abstract: The response of climate to freshwater input in the North Atlantic (NA) has raised a lot of concern about the issue of climate stability since the discovery of abrupt coolings during the last glacial period. Such coolings ...
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 ...
Impact of the Ocean Mixed Layer Diurnal Variations on the Intraseasonal Variability of Sea Surface Temperatures in the Atlantic Ocean
Publisher: American Meteorological Society
Abstract: his study investigates the nonlinear processes by which the ocean diurnal variations can affect the intraseasonal sea surface temperature (SST) variability in the Atlantic Ocean. The Centre National de Recherches Météorologiques ...
Progress in Paleoclimate Modeling
Publisher: American Meteorological Society
Abstract: This paper briefly surveys areas of paleoclimate modeling notable for recent progress. New ideas, including hypotheses giving a pivotal role to sea ice, have revitalized the low-order models used to simulate the time ...
