Resumen:
In this paper, we analyzed the climate
changes simulated over Argentina and surrounding
countries under two IPCC emission scenarios
(A2 and B2) for the period 2081-2090 with respect
to the reference period 1981-1990. The simulations
are performed with the regional climate
model MM5 using forcing lateral boundary conditions
from time-slice simulations with the HAdAM3P
global atmospheric model. Our primary
conclusions can be summarized as follows:
The MM5 Regional Climate Model simulate
current climate more realistically and
project climate change with greater detail.
In all seasons, southern South America
undergoes warming in both the A2 and B2
scenarios. Minimum changes in the Mean
Temperature are projected for summer
and fall over the domain (2.5 - 3.5 ° C in
the A2 simulation).In all seasons, southern South America

Maximum changes in the Mean Temperature

The precipitation changes vary substantially
from season to season and across
regions in response to changes in large
scale circulations. Seasonal changes in
precipitation in Argentina are projected for
summer and fall seasons (west and humid
Pampas increase approximately 180 mm
maximum per season in the A2 simulation).The precipitation changes vary substantially
