  1. Performance of high resolution global model over La Plata Basin Mario N. Nuñez CIMA-DCAO CONICET / UBA UMI IFAECI 2nd Meeting Buenos Aires, Argentina April 25-27, 2011

  2. Ongoing research in the climate of Southern South America Mario N. Nuñez CIMA-DCAO CONICET / UBA UMI IFAECI 2nd Meeting Buenos Aires, Argentina April 25-27, 2011

  3. Performance of high resolution global model over La Plata Basin Josefina Blazquez and Mario Nuñez Objective: To provide an evaluation of a present climate simulation over La Plata Basin and to understand the futures climate changes.

  4. Global Model: MRI/JMA Resolution: 20 km and 60 km (3 members) Period: 1979-2003 Initial condition: Observed SST (Rayner et al. 2003)

  5. PRELIMINARY RESULTS

  6. Precipitación (mm/day)

  7. Regional Climate Change Simulations over Southern South Americawith the MM5/CIMA model forced by the global HadAM3H model María Fernanda Cabré, Mario Nuñez and Silvina Solman

  8. We present an analysis of a regional climate change simulation over southern South America. The MM5/CIMA model was forced by the global atmospheric model HadAM3H. 20 years for the present climate(1970-1999). 20 years for the future climate(2080-2099).

  9. PRELIMINARY RESULTS

  10. Precipitation (mm/day). Present-Day climate 1970-1999 Fig 1 b) Average precipitation for present from the regional model MM5 (left panels) and from observations CRU (right panels)

  11. Mean Temperature (ºC) Fig 2 b) Seasonal mean of surface air temperature for present from the regional model MM5 (left panels) and from observations CRU (right panels)

  12. Precipitation Changes (mm/day) SRES A2 (2080-2099) Fig 3 Precipitation seasonal changes from regional model MM5

  13. Mean Temperature Changes (ºC) SRES A2 (2080-2099) Fig 4 Mean Temperature seasonal changes from regional model MM5

  14. The regional water cycle and surface energy processes of the La Plata basinH. Berbery, A. Rolla and M. Nuñez Our particular interest is the evaluation of the annual cycle of the hydrological cycle components. We performed numerical experiments using the HRLDAS (High Resolution Land Data Assimilation System) 3.2 model. The terrestrial water cycle and all energy related computations were analyzed here using a 26-year long (1980 to 2006) data set.

  15. PRELIMINARY RESULTS

  16. Some applications… Drought Indexes Period 1980-2006. Meteorological (top), hydrological (center) and agricultural drought (botton).

  17. We are now searching for observations, mainly, of soil moisture, to validate the model results
