TIME OPINION TECNICA SOBRE EL MODELO
ETA – 22 km - Peru
Regional c/6 hours 22 km Modelo GFS Operational Dell Presicio 470Server
1 Year This Model works good with irregular topographies, specially with a large slope like peruvian higlands.I has an adjunsting to the convection scheme.
ETA-32km – South América
Regional c/6 hours 32 km Modelo GFS Operational Dell Presicio 470Server
1 Year
WRF-33km Regional c/6 hours 33 km Modelo GFS Testing Sun Fire V40ZServer
MIDDLE LAST YEAR
WRF is a new generation mesoscale model prediction, designed to operational forecast and atmospheric research.It has the best of Eta, MM5 en others.
WRF-22km Regional c/6 hours 22 km Modelo GFS Testing Sun Fire V40ZServer
WRF-Nested Regional c/6 hours 36 km/12 km 36 km-Model GFS12km-nested whit 36 km

Testing HP Proliant DL 380 G5Server
ENDING LAST YEAR
BRAMS is a brazilian versión of RAMS model adapted to the tropics, it makes simulation of atmospheric circulations to several spatial scales..
CCM3 Global Monthly 2.8° TSM Reynolds NOAA
Adaptado COMPAQ Alpha ES40Server
8 Years This model support to stational forecast. However there are new versions , in this sense we are trying to implement the CAM model.
