Title - SALLJEX Model Meteorology CPTEC (Brazil) Forecast Products: Global 80 km

SALLJEX Coordinated model experiment 1
.....................................................

Description:

These  results correspond to the SALLJEX experiment, using the 
Atmospheric Global Circulation Model CPTEC/COLA, with  a high 
resolution of T170 L42, that represents triangular truncation 
of 170 waves in the horizontal coordinate and 42 levels in the 
vertical sigma coordinate. This resolution corresponds to the 
required resolution of 80 km.

CPTEC/COLA GCM is a modified version of the spectral COLA GCM, 
which was adapted from the National Centers for Environmental 
Prediction (NCEP) GCM. The dynamical and physical processes in 
the COLA model are described in Kinter et al. (1997). The 
CPTEC/COLA model dynamical processes and physical 
parameterizations are the same as those of COLA model, with Kuo 
scheme for deep convection (Kuo 1974); shallow convection 
following Tiedke (1983); Mellor and Yamada closure scheme 
applied for the vertical diffusion in the planetary boundary 
layer (Mellor and Yamada 1982) and biharmonic type diffusion for 
the horizontal diffusion which is necessary to control small 
scale noise. The shortwave radiation is that of Lacis and Hansen 
(1974), modified by Davies (1982) and the longwave radiation 
formulation was that developed by Hashvardhan et al. (1987). 
Cloud-radiation interaction considers predicted clouds using a 
hybrid scheme of Hou (1990) and NCAR CCM2 scheme (Kihel et al. 
1994). The Hou scheme is based on cloud prediction of Slingo 
(1987). More information  about the model can be found in 
Cavalcanti, IFA, et al., 2002. Global climatological features in 
a simulation using CPTEC/COLA AGCM. J.Climate, 15, 2965-2988.
