Climatic Impact of Global-Scale Deforestation: Radiative versus Nonradiative Processes
Publisher: American Meteorological Society
Abstract: A fully coupled land?ocean?atmosphere GCM is used to explore the biogeophysical impact of large-scale deforestation on surface climate. By analyzing the model sensitivity to global-scale replacement of forests by grassland, ...
Hot Desert Albedo and Climate Change: Mid-Holocene Monsoon in North Africa
Publisher: American Meteorological Society
Abstract: Many models in the framework of the Paleoclimate Modelling Intercomparison Project have undertaken simulations of the mid-Holocene (6 kyr ago) climate change. Analysis of the results have mainly focused on the North African ...
Vegetation Dynamics Enhancing Long-Term Climate Variability Confirmed by Two Models
Publisher: American Meteorological Society
Abstract: wo different coupled climate?vegetation models, the Community Climate Model version 3 coupled to the Integrated Biosphere Simulator (CCM3?IBIS) and the Laboratoire de Météorologie Dynamique?s climate model coupled to the ...
Quantifying the Relative Importance of Direct and Indirect Biophysical Effects of Deforestation on Surface Temperature and Teleconnections
Publisher: American Meteorological Society
Abstract: AbstractIn this study, the authors linearize the surface energy budget equation that disentangles indirect effects (resulting from changes in downward shortwave and longwave radiation and air temperature) from direct ...
Hot European Summers and the Role of Soil Moisture in the Propagation of Mediterranean Drought
Publisher: American Meteorological Society
Abstract: Drought in spring and early summer has been shown to precede anomalous hot summer temperature. In particular, drought in the Mediterranean region has been recently shown to precede and to contribute to the development of ...
Including Croplands in a Global Biosphere Model: Methodology and Evaluation at Specific Sites
Publisher: American Meteorological Society
Abstract: There is a strong international demand for quantitative estimates of both carbon sources/sinks, and water availability at the land surface at various spatial scales (regional to global). These estimates can be derived (and ...
Determining Robust Impacts of Land-Use-Induced Land Cover Changes on Surface Climate over North America and Eurasia: Results from the First Set of LUCID Experiments
Publisher: American Meteorological Society
Abstract: he project Land-Use and Climate, Identification of Robust Impacts (LUCID) was conceived to address the robustness of biogeophysical impacts of historical land use?land cover change (LULCC). LUCID used seven atmosphere?land ...
