Implementation of a Real-Time Short Range Ensemble Forecasting System at NCEP: An Update
A regional-model based Short-Range Ensemble Forecasting (SREF) system
is scheduled for implementation on a real-time basis in May 2001. The
system consists of 10 members, five each generated with the Eta and
Regional Spectral Model (RSM), with perturbations to initial conditions
provided by "regional breeding". The ensemble system will run twice
daily from 09Z and 21Z through 63 hours and be available about the same
time as the 12Z and 00Z operational Eta runs. The SREF system will be
described futher in this presentation with emphasis on relevance to
operational applications and system performance, including comparison
of the information content of this relatively lower-resolution ensemble
with the higher-resolution deterministic runs of the Eta. Finally,
plans for upgrading the SREF system will be outlined.
