The rich mesoscale information in NSCAT winds over tropical coastal regions is used in numerical simulations of two June 1997 monsoonal cases occurring over Taiwan. It is shown that transient NSCAT mesoscale information over a localized area as small as 120 km × 240 km can result in significant improvement in the 24 h heavy rainfall forecast due to its effect on monsoonal convection and terrain effects.
