NCEP NAM CONUS Graphics - NAM Forecast vs RTMA Analyses
This page is a comparison of the North American Meso (NAM) forecast from 12Z 03 MAY 2012
and the best available Real-time Mesoscale Analysis (RTMA) valid at the same time.
When any of the forecast hour links on the left is activated, the following
charts will be displayed:
Upper left : NAM forecast (Eastern U.S.)
Upper right : NAM forecast (Western U.S.)
Lower left : RTMA analysis (Eastern U.S.)
Upper right : RTMA analysis (Western U.S.)
NOTE : For sea level pressure/850 mb/500 mb/250 mb fields, the NDAS analysis is displayed
- For regional 10-m winds, surface wind observations are also displayed.
- For regional 2-m temperatures and dew point temperatures, observations valid at that time also displayed.
- All displayed winds are in knots.
