RISAmazonian Deforestation: Impact of Global Warming on the Energy Balance and Climate
Publisher: American Meteorological Society
Abstract: coupled biosphere?atmosphere statistical?dynamical model is used to study the relative roles of the impact of the land change caused by tropical deforestation and global warming on energy balance and climate. Three experiments ...

Genesis of the Northeast Brazil Upper-Tropospheric Cyclonic Vortex: A Primitive Equation Barotropic Instability Study
Publisher: American Meteorological Society
Abstract: The primitive equation barotropic unstable linear normal modes are computed using an eigenvalue approach for daily latitudinal profiles of zonal flow in the upper-tropospheric layer of 100?350 hPa before and after formation ...
Monsoonlike Circulations in a Zonally Averaged Numerical Model with Topography
Publisher: American Meteorological Society
Abstract: A primitive equation global zonally averaged general circulation model is used to study the effects of the topography on the atmospheric annual cycle. A smoothed zonally averaged topography that has a form similar to that ...
A Diagnosis of Rainfall over South America during the 1997/98 El Niño Event. Part I: Validation of NCEP–NCAR Reanalysis Rainfall Data
Publisher: American Meteorological Society
Abstract: A comparison between the National Centers for Environmental Predictions?National Center for Atmospheric Research (NCEP?NCAR) reanalysis rainfall data and the Agência Nacional de Energia Elétrica (ANEEL) rain gauge data ...
A Coupled Biosphere–Atmosphere Climate Model Suitable for Studies of Climatic Change Due to Land Surface Alterations
Publisher: American Meteorological Society
Abstract: A biosphere model based on BATS (Biosphere?Atmosphere Transfer Scheme) is coupled to a primitive equation global statistical?dynamical model in order to study the climatic impact due to land surface alterations. The fraction ...
Rainy-Season Duration Estimated from OLR versus Rain Gauge Data and the 2001 Drought in Southeast Brazil
Publisher: American Meteorological Society
Abstract: Large precipitation deficits observed during the 2001 austral summer over the southeast region of Brazil contributed to the worsening of the energy crisis that was occurring in the country, with unprecedented social and ...
Interaction between Coastal Upwelling and Local Winds at Cabo Frio, Brazil: An Observational Study
Publisher: American Meteorological Society
Abstract: The relationships between coastal upwelling and local winds at Cabo Frio (Brazil) are studied using SST and time series of surface wind for a 10-yr period (1971?80). The results show that the seasonal variations of SST and ...
Seasonal Variations in the Southern Hemisphere Storm Tracks and Associated Wave Propagation
Publisher: American Meteorological Society
Abstract: Seasonal variations in the Southern Hemisphere (SH) storm track characteristics and associated wave propagation are studied using 19 years of NCEP?NCAR gridded data. It is found that the SH storm track is strongest in the ...
A Diagnosis of Rainfall over South America during the 1997/98 El Niño Event. Part II: Roles of Water Vapor Transport and Stationary Waves
Publisher: American Meteorological Society
Abstract: A diagnosis of rainfall over South America (SA) during the 1997/98 El Niño year is made examining the roles of water vapor transport and stationary waves. It is found that the low-level jet (LLJ) on the eastern side of the ...
