RISDynamic Downscaling of Seasonal Climate Predictions over Brazil
Publisher: American Meteorological Society
Abstract: Climate projections for March?April?May (MAM) 1985 and 1997 made with the NASA Goddard Institute for Space Studies (GISS) GCM over South America on a 4° latitude by 5° longitude grid are ?downscaled? to 0.5° grid spacing. ...
Case Studies of African Wave Disturbances in Gridded Analyses
Publisher: American Meteorological Society
Abstract: African wave disturbances (AWDs), an important trigger of Sahel summer rainfall, are studied using ECMWF gridded datasets for July and August 1987 and 1988. Power spectra of time series of 700-mb meridional winds near ...
Climate Change and the Middle Atmosphere. Part IV: Ozone Response to Doubled CO2
Publisher: American Meteorological Society
Abstract: Parameterized stratospheric ozone photochemistry has been included in the Goddard Institute for Space Studies (GISS) GCM to investigate the coupling between chemistry and climate change for the doubled CO2 climate. The ...
A Regional Model Study of Synoptic Features over West Africa
Publisher: American Meteorological Society
Abstract: Synoptic weather features over West Africa were studied in simulations by the regional simulation model (RM) at the NASA Goddard Institute for Space Studies. These pioneering simulations represent the beginning of an effort ...
The Relative Importance of Solar and Anthropogenic Forcing of Climate Change between the Maunder Minimum and the Present
Publisher: American Meteorological Society
Abstract: The climate during the Maunder Minimum is compared with current conditions in GCM simulations that include a full stratosphere and parameterized ozone response to solar spectral irradiance variability and trace gas changes. ...
