The HWRF model is an
important component of the guidance used at the National Hurricane Center,
making it critical that HWRF be continuously improved. For that reason, the
NOAA/NCEP Environmental Modeling Center (EMC) has partnered with the
Developmental Testbed Center (DTC) to accelerate the transfer of new
developments onto HWRF.
The atmospheric
component of HWRF is a configuration of the WRF model which has recently been
advanced to include a revised nest motion algorithm and an observations-based
boundary layer parameterization scheme that were developed by NCEP/EMC and NOAA/AOML Hurricane Research
Division. HWRF's oceanic component is a version of the Princeton Ocean Model
adapted for tropical cyclones, which was developed at the University of Rhode
Island. Additionally, HWRF uses vortex cycling for atmospheric initialization,
a feature-based ocean initialization, and a tracker to extract information from
the output.
In this presentation, we
will give an overview of community HWRF v3.3a released in 2011, and discuss the
2012 operational configuration and the new capabilities users can expect in the
upcoming HWRF v3.4a release.
