Abstract: Major revisions to the Geophysical Fluid Dynamics Laboratory's (GFDL) continuous data-assimilation system have been implemented and tested. Shortcomings noted during the original processing of data from FGGE [First GARP ...

Abstract: Spectral atmospheric general circulation models (GCMS) have been used for many years for the simulation and prediction of the atmospheric circulation, and their value has been widely recognized. Over the years, however, ...

Abstract: This study compares the tropical intraseasonal oscillation (TISO) variability in the Geophysical Fluid Dynamics Laboratory (GFDL) coupled general circulation model (CGCM) and the stand-alone atmospheric general circulation ...

Abstract: The reanalysis of FGGE (First GARP (Global Atmospheric Research Program) Global Experiment) data for 128 days during two special observing periods has been performed, using an improved data-assimilation system and the ...

Abstract: Tropical storms simulated by a nine-member ensemble of GCM integrations forced by observed SSTs have been tracked by an objective procedure for the period 1980?88. Statistics on tropical storm frequency, intensity, and ...

Abstract: The present study examines the simulation of the number of tropical storms produced in GCM integrations with a prescribed SST. A 9-member ensemble of 10-yr integrations (1979?88) of a T42 atmospheric model forced by observed ...

Abstract: ropical cyclones (TCs) are a hazard to life and property and a prominent element of the global climate system; therefore, understanding and predicting TC location, intensity, and frequency is of both societal and scientific ...

Abstract: The atmospheric anomalies for the 1997/98 El Niño?Southern Oscillation (ENSO) period have been analyzed and intercompared using the data simulated by the atmospheric general circulation models (GCMs) of 11 groups participating ...
