This study compares the ability of monthly total precipitable water analyses from the National Aeronautics and Space Administration Water Vapor Project (NVAP), National Centers for Environmental Prediction (NCEP) reanalysis (R-1), NCEP-Department of Energy (DOE) Atmospheric Model Intercomparison Project (AMIP-II) reanalysis (R-2), European Centre for Medium-Range Weather Forecasts (ECMWF) reanalysis (ERA-15), and ECMWF reanalysis (ERA-40) from January 1988 through December 1999 in resolving convergence and/or moist-air advection zones. By applying a Clausius-Clapeyron type equation and using annual means, only ERA-40 can well represent convergence and/or wet air advection zones in the tropics. The pattern of the zones over the tropical ocean is comparable to the precipitation pattern over the ocean suggesting ERA-40's potential utility in TPW interannual variability studies.
