Abstracts

WMO mission to Hanoi in February 2011 determined that the NCHMF appeared to have an excellent development potential to undertake the role of the Regional Forecasting Support Centre (RFSC) in the Severe Weather Forecasting Demonstration Project for Southeast Asia project. To provide better product for developing the guidances for SWFDP-SeA, based on new capacities of High Performance Computing (HPC) of VNMHA, this paper presents new high-resolution numerical weather prediction products including very high-resolution deterministic products (WRF3kmIFS) and high-resolution regional ensemble systems (SREPS-32). WRF3kmIFS is configed by using the recently released version of Weather Research and Forecasting model with ARW dynamical core - WRF-ARW (version 3.9.1.1) with IFS (ECMWF) for boudary conditions while SREPS-32 is a set of combination of physical parameterizations. Some improved performances are shown relating to heavy rainfall and tropical cyclone over Southeast Asian domain and for the South East Asia Flash Flood Guidance Systems.
