Atmospheric circulation, precipitation and temperature in the South American monsoon region

PI: Iracema F.A. Cavalcanti
Institution: Centro de Previsao de Tempo e Estudos Climaticos
Additional Investigators: Pedro L. Silva Dias, Dirceu Herdies, Christopher C Cunningham, Helio Camargo, Tatiana Tarasova, Kelen Andrade
Objective: To identify in the future scenarios, changes in the atmospheric circulation patterns and climate variables over South America and nearby oceans, related to the life cycle of the South America Monsoon. The purpose is to analyze changes in precipitation, temperature over South America, considering different regions, different regimes and changes that can occur in climatological systems, as the Bolivia High, Upper level Cyclone Vortex over the Atlantic Ocean, Intertropical Convergence Zone, South Atlantic Convergence Zone, Atlantic and Pacific Subtropical Highs, Jet streams, Annual Cycle of precipitation over northern and southern South America, SW radiation. Changes in tropical convection of other regions and connections with changes over South America will also be investigated using different statistical techniques, including clustering analysis, empirical orthogonal functions. Of particular interest is the analysis of changes in the general characteristics of the Southern Hemisphere teleconnection patterns relevant to S. American climate.

Model data required: Monthly data of: Precipitation, Surface temperature, OLR, zonal and meridional wind components at 1000, 925, 850, 700, 500, 300, 200 and 100 hPa, geopotential height at 500, 300 and 200 hPa, Sea Level Pressure, soil moisture, specific humidity at 1000, 925, 850, 700, 500 hPa, Temperature at 1000, 925, 850, 700, 500, 300, 200 and 100 hPa.
