RISDynamical Downscaling over the Great Lakes Basin of North America Using the WRF Regional Climate Model: The Impact of the Great Lakes System on Regional Greenhouse Warming
Publisher: American Meteorological Society
Abstract: he Weather Research and Forecasting model (WRF) is employed to dynamically downscale global warming projections produced using the Community Climate System Model (CCSM). The analyses are focused on the Great Lakes Basin ...
A Dynamical Systems Model of the Dansgaard–Oeschger Oscillation and the Origin of the Bond Cycle
Publisher: American Meteorological Society
Abstract: A low-dimensional dynamical systems model of the North Atlantic thermohaline circulation has been developed in order to better understand the mechanism underlying the so-called Dansgaard?Oeschger oscillation that is so ...
Dynamically Downscaled Climate Simulations of the Indian Monsoon in the Instrumental Era: Physics Parameterization Impacts and Precipitation Extremes
Publisher: American Meteorological Society
Abstract: AbstractThe complex orography of South Asia, including both the Himalayas and the Tibetan Plateau, renders the regional climate complex. How this climate, especially the monsoon circulations, will respond to the global ...
Fast Physics and Slow Physics in the Nonlinear Dansgaard–Oeschger Relaxation Oscillation
Publisher: American Meteorological Society
Abstract: AbstractThe Dansgaard?Oeschger (D-O) relaxation oscillation that governed glacial climate variability during marine isotope stage 3 has been accurately simulated using a high-resolution coupled climate model. Here the ...
Implications of Both Statistical Equilibrium and Global Warming Simulations with CCSM3. Part II: On the Multidecadal Variability in the North Atlantic Basin
Publisher: American Meteorological Society
Abstract: The nature of the multidecadal variability in the North Atlantic basin is investigated through detailed analysis of multicentury integrations performed using the low-resolution version of the Community Climate System Model, ...
Projected Hydroclimatic Changes in Two Major River Basins at the Canadian West Coast Based on High-Resolution Regional Climate Simulations
Publisher: American Meteorological Society
Abstract: AbstractThe impact of anthropogenic climate change on water resources and flood and drought risk is of great interest for impact modeling and to inform adaptation strategies. Here an analysis of hydroclimatic changes in ...
Modeling of Polar Ocean Tides at the Last Glacial Maximum: Amplification, Sensitivity, and Climatological Implications
Publisher: American Meteorological Society
Abstract: Diurnal and semidiurnal ocean tides are calculated for both the present day and the Last Glacial Maximum. A numerical model with complete global coverage and enhanced resolution at high latitudes is used including the ...
Implications of Both Statistical Equilibrium and Global Warming Simulations with CCSM3. Part I: On the Decadal Variability in the North Pacific Basin
Publisher: American Meteorological Society
Abstract: In the low-resolution version of the Community Climate System Model, version 3 (CCSM3), the modeled North Pacific decadal variability is demonstrated to be independent of the epoch for which a statistically steady control ...
The Initiation of Modern “Soft Snowball” and “Hard Snowball” Climates in CCSM3. Part II: Climate Dynamic Feedbacks
Publisher: American Meteorological Society
Abstract: his study investigates the climate dynamic feedbacks during a transition from the present climate to the extremely cold climate of a ?Snowball Earth? using the Community Climate System Model, version 3 (CCSM3). With the ...
The Initiation of Modern “Soft Snowball” and “Hard Snowball” Climates in CCSM3. Part I: The Influences of Solar Luminosity, CO2 Concentration, and the Sea Ice/Snow Albedo Parameterization
Publisher: American Meteorological Society
Abstract: he ?Snowball Earth? hypothesis, proposed to explain the Neoproterozoic glacial episodes in the period 750?580 million years ago, suggested that the earth was globally covered by ice/snow during these events. This study ...
