To be submitted. ------------------------------------------------------------------- Experiment I: CDAS-I Resolution: T62L28 (about 210 km) L28 ............................................................. Description: These results correspond to the SALLJEX experiment, using the Atmospheric Global Circulation Model, with a resolution of T062 L28, that represents triangular truncation of 62 waves in the horizontal coordinate and 28 levels in the vertical sigma coordinate. This resolution corresponds to approximatelly 210 km. For more references about the model and analysis system please refer to: Kalnay et al. 1996: The NCEP/NCAR 40 Year Reanalysis Project. Bull.
