RISComparison of the Impact of the 1982/83 and 1986/87 Pacific SST Anomalies on Time-Mean Predictions of Atmospheric Circulation
Publisher: American Meteorological Society
Abstract: The primary focus of this study is to contrast the impact of the El Niño Pacific sea surface temperature (SST) anomalies observed during the Northern Hemisphere winters of 1982/83 and 1986/87 on predictions with a global ...
Prediction of Time-Mean Atmospheric Circulation and Rainfall: influence of Pacific Sea Surface Temperature Anomaly
Publisher: American Meteorological Society
Abstract: A global general circulation model was integrated for 60 days with the observed initial conditions at 0000 UTC on 15, 16 and 17 December 1982 and climatological boundary conditions of sea surface temperature (SST), soil ...
Seasonal Prediction over North America with a Regional Model Nested in a Global Model
Publisher: American Meteorological Society
Abstract: Ensembles of winter and summer seasonal hindcasts have been carried out with an 80-km resolution version of the National Centers for Environmental Prediction, Environmental Modeling Center Eta model over the North American ...
Impact of Initial Soil Wetness on Seasonal Atmospheric Prediction
Publisher: American Meteorological Society
Abstract: This study investigates the importance of initial soil wetness in seasonal predictions with dynamical models. Two experiments are performed, each consisting of two ensembles of global climate model integrations initialized ...
Numerical Simulation of the Atmospheric Response to the Time-Varying El Niño SST Anomalies during May 1982 Through October 1983
Publisher: American Meteorological Society
Abstract: A general circulation model was first integrated for 25 months with monthly climatological boundary conditions of sea surface temperature (SST), soil moisture, sea ice and albedo. Starting from day 165 of this ?control? ...
General Circulation Model Sensitivity to 1982–83 Equatorial Pacific Sea Surface Temperature Anomalies
Publisher: American Meteorological Society
Abstract: Three control and anomaly simulation pairs run with the Goddard Laboratory for Atmospheric Sciences (GLAS) climate model have been analyzed in order to investigate the atmospheric response to the 1982?83 tropical sea surface ...
The Influence of Initial Soil Wetness on Medium-Range Surface Weather Forecasts
Publisher: American Meteorological Society
Abstract: The influence of initial soil wetness on surface weather forecasts was quantitatively assessed through the use of the Center for Ocean?Land?Atmosphere Interactions (COLA) general circulation model with an advanced simple ...
Climatic Feedbacks during the 2003 European Heat Wave
Publisher: American Meteorological Society
Abstract: uring the summer of 2003, a record heat wave over Europe occurred, to which the deaths of over 20 000 people in 18 countries were attributed, 10 000 of those in France alone. Temperatures across Europe were above normal ...
An Evaluation of the Apparent Interdecadal Shift in the Tropical Divergent Circulation in the NCEP–NCAR Reanalysis
Publisher: American Meteorological Society
Abstract: Recent decadal regime shifts in the large-scale circulation of the tropical atmosphere are examined using analyses and independent observations of the circulation and precipitation. Comparisons between reanalysis products ...
The Simulated Indian Monsoon: A GCM Sensitivity Study
Publisher: American Meteorological Society
Abstract: A series of sensitivity experiments are conducted in an attempt to understand and correct deficiencies in the simulation of the seasonal mean Indian monsoon with a global atmospheric general circulation model. The seasonal ...
