RISPotential Impact of the Eurasian Boreal Forest on North Pacific Climate Variability
Publisher: American Meteorological Society
Abstract: The authors demonstrate that variability in vegetation cover can potentially influence oceanic variability through the atmospheric bridge. Experiments aimed at isolating the impact of variability in forest cover along the ...
Extracting the Dominant SST Modes Impacting North America's Observed Climate
Publisher: American Meteorological Society
Abstract: he seasonal impacts of the dominant sea surface temperature (SST) modes to North American climate are assessed comprehensively in observations using the multivariate generalized equilibrium feedback assessment (GEFA) method. ...
Improving Climate Sensitivity of Deep Lakes within a Regional Climate Model and Its Impact on Simulated Climate
Publisher: American Meteorological Society
Abstract: egional climate models aim to improve local climate simulations by resolving topography, vegetation, and land use at a finer resolution than global climate models. Lakes, particularly large and deep lakes, are local features ...
A Mechanism for Abrupt Climate Change Associated with Tropical Pacific SSTs
Publisher: American Meteorological Society
Abstract: The tropical Pacific?s response to transiently increasing atmospheric CO2 is investigated using three ensemble members from a numerically efficient, coupled atmosphere?ocean GCM. The model is forced with a 1% yr?1 increase ...
The Role of Ice Cover in Heavy Lake-Effect Snowstorms over the Great Lakes Basin as Simulated by RegCM4
Publisher: American Meteorological Society
Abstract: 20-km regional climate model, the Abdus Salam International Centre for Theoretical Physics Regional Climate Model version 4 (ICTP RegCM4), is employed to investigate heavy lake-effect snowfall (HLES) over the Great Lakes ...
Global Vegetation and Climate Change due to Future Increases in CO2 as Projected by a Fully Coupled Model with Dynamic Vegetation
Publisher: American Meteorological Society
Abstract: Transient simulations are presented of future climate and vegetation associated with continued rising levels of CO2. The model is a fully coupled atmosphere?ocean?land?ice model with dynamic vegetation. The impacts of the ...
A GEFA Assessment of Observed Global Ocean Influence on U.S. Precipitation Variability: Attribution to Regional SST Variability Modes
Publisher: American Meteorological Society
Abstract: This paper presents a comprehensive assessment of the observed influence of the global ocean on U.S. precipitation variability using the method of Generalized Equilibrium Feedback Assessment (GEFA), which enables an ...
Vegetation Feedbacks to Climate in the Global Monsoon Regions
Publisher: American Meteorological Society
Abstract: egetation feedbacks on climate, on the subannual time scale, are examined across six monsoon regions with a fully coupled atmosphere?ocean?ice?land model with dynamic vegetation. Initial value ensemble experiments are run ...
Dynamically Downscaled Projections of Lake-Effect Snow in the Great Lakes Basin
Publisher: American Meteorological Society
Abstract: rojected changes in lake-effect snowfall by the mid- and late twenty-first century are explored for the Laurentian Great Lakes basin. Simulations from two state-of-the-art global climate models within phase 5 of the Coupled ...
Dynamical Downscaling–Based Projections of Great Lakes Water Levels
Publisher: American Meteorological Society
Abstract: rojections of regional climate, net basin supply (NBS), and water levels are developed for the mid- and late twenty-first century across the Laurentian Great Lakes basin. Two state-of-the-art global climate models (GCMs) ...
