Impact of New Solar Radiation Parameterization in the Eta Model on the Simulation of Summer Climate over South America

Source: Journal of Applied Meteorology and Climatology:;2006:;volume( 045 ):;issue: 002:;page 318

Author(s): Tarasova, T. A.; Fernandez, J. P. R.; Pisnichenko, I. A.; Marengo, J. A.; Ceballos, J. C.; Bottino, M. J.

Publisher: American Meteorological Society

Abstract: The regional Eta workstation (WS) model with horizontal resolution of 40 km has been integrated over South America for January 2003. The NCEP?DOE Reanalysis II was used for initial and lateral boundary conditions. The ...

Seasonal-to-Decadal Predictability and Prediction of South American Climate

Source: Journal of Climate:;2006:;volume( 019 ):;issue: 023:;page 5988

Author(s): Nobre, P.; Marengo, J. A.; Cavalcanti, I. F. A.; Obregon, G.; Barros, V.; Camilloni, I.; Campos, N.; Ferreira, A. G.

Publisher: American Meteorological Society

Abstract: The dynamical basis for seasonal to decadal climate predictions and predictability over South America is reviewed. It is shown that, while global tropical SSTs affect both predictability and predictions over South America, ...

Advancing Global-and Continental-Scale Hydrometeorology: Contributions of GEWEX Hydrometeorology Panel

Source: Bulletin of the American Meteorological Society:;2004:;volume( 085 ):;issue: 012:;page 1917

Author(s): Lawford, R. G.; Stewart, R.; Roads, J.; Isemer, H-J.; Manton, M.; Marengo, J.; Yasunari, T.; Benedict, S.; Koike, T.; Williams, S.

Publisher: American Meteorological Society

Abstract: Over the past 9 years, the Global Energy and Water Cycle Experiment (GEWEX), under the auspices of the World Climate Research Programme (WCRP), has coordinated the activities of the Continental Scale Experiments (CSEs) and ...

The South American Low-Level Jet Experiment

Source: Bulletin of the American Meteorological Society:;2006:;volume( 087 ):;issue: 001:;page 63

Author(s): Vera, C.; Baez, J.; Douglas, M.; Emmanuel, C. B.; Marengo, J.; Meitin, J.; Nicolini, M.; Nogues-Paegle, J.; Paegle, J.; Penalba, O.; Salio, P.; Saulo, C.; Silva Dias, M. A.; Silva Dias, P.; Zipser, E.

Publisher: American Meteorological Society

Abstract: Moisture is transported in South America westward from the tropical Atlantic Ocean to the Amazon basin, and then southward toward the extratropics. A regional intensification of this circulation to the east of the Andes ...

Toward a Unified View of the American Monsoon Systems

Source: Journal of Climate:;2006:;volume( 019 ):;issue: 020:;page 4977

Author(s): Vera, C.; Higgins, W.; Amador, J.; Ambrizzi, T.; Garreaud, R.; Gochis, D.; Gutzler, D.; Lettenmaier, D.; Marengo, J.; Mechoso, C. R.; Nogues-Paegle, J.; Dias, P. L. Silva; Zhang, C.

Publisher: American Meteorological Society

Abstract: An important goal of the Climate Variability and Predictability (CLIVAR) research on the American monsoon systems is to determine the sources and limits of predictability of warm season precipitation, with emphasis on ...
