NWP models

The NWP models evaluated are:  

GFS: The U.S. NCEP Global Forecast System;     
FNO: The U.S. Navy Fleet Numerical Meteorology and Oceanograpy Center;    
ECM: European Center for Medium-Range Weather Forecasts;    
UKM: The United Kingdom Met Office;    
CMC: The Canadian Meteorological Center;    
JMA: Japan Meteorological Agency;    
CDAS: The frozen version of GFS used for the NCEP/NCAR Reanalysis Project. 


The regions referred to are:  
G2 (GLB): Globe    
NHX: 20N-80N     
SHX: 20S-80S     
TRO: 20S-20N


Pattern correlations for all NWP models are computed using anomalies respective to a 30-year (1959-1988) climatology of the NCEP/NCAR reanalysis.
