RISMoist Baroclinic Instability in the Development of North Pacific and South American Intermediate-Scale Disturbances
Publisher: American Meteorological Society
Abstract: The Mak parameterization of latent heat release is discussed using a finite difference version of a quasigeostrophic ?-plane model. It is found that his analytical results can be well reproduced with 20-layer vertical ...
Experiments with EOF-Based Perturbation Methods and Their Impact on the CPTEC/INPE Ensemble Prediction System
Publisher: American Meteorological Society
Abstract: The impact of modifications of the perturbation method based on empirical orthogonal functions (EOFs) used operationally upon the ensemble prediction system (EPS) at the Center for Weather Prediction and Climate Studies/National ...
Diurnally Forced Tropical Tropospheric Circulation over South America
Publisher: American Meteorological Society
Abstract: The impact of diurnally varying thermal forcing on the tropical circulation is studied with a linearized shallow water model on an equatorial beta plane. The mass and flow fields are interpreted as an internal mode with ...
Global Climatological Features in a Simulation Using the CPTEC–COLA AGCM
Publisher: American Meteorological Society
Abstract: The Center for Weather Forecasting and Climate Studies?Center for Ocean?Land?Atmosphere Studies (CPTEC?COLA) atmospheric general circulation model (AGCM) is integrated with nine initial conditions for 10 yr to obtain the ...
