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.


Global Model: BasinMRI/JMA

Resolution: 20 km and 60 km (3 members)

Period: 1979-2003

Initial condition: Observed SST (Rayner et al. 2003)




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


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).

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.
