VERIFICATION OF WRF SUMMER RAINFALL FORECASTS OVER THE SOUTH AND CENTRAL HIGHLAND OF VIET NAM IN ASSOCIATED WITH TYPHOONS IN THE VIET NAM EAST SEA

Abstract

This study examines rainfall forecasting skills of WRF model over the South and the Southern part of Central Highlands in associated with tropical storm activity in the East Sea in the period 2010-2014. The initial and boundary conditions for the WRF model are from the NCEP-GFS model with a horizontal resolution of 0.5x0.5 degrees. The observed rainfall data at 17-surface stations were used to validate the model skills. The results show that the WRF model tends to oversimulate rainfall. In case of heavy rainfall caused by Utor typhoon, the model (WRF model) simulates quite well rainfall distribution for the specific research site. It is also able to capture as well some local extreme rainfall events.
