Daily-mean reanalyses from the National Centers for Environmental Prediction/Na tional Center for Atmospheric Research (NCEP/NCAR) for the years 1980-1989 are used as verification data in a study of intraseasonal oscillation (IO) in the GOALS/LASG coupled general circulation model. The projection of the IO onto the upper troposphere zonal wind provides a useful measure of intraseasonal activities. The results show that GOALS/LASG captures the salient features of IO in the tropics. The simulated IO is more...
