- HWRF Version 3.3a
- WRF model upgraded to WRF v3.3a, the HWRF 2011 Operational Capability added to WRF v3.3
- Simplified Arakawa Schubert (SAS) cumulus parameterization scheme upgraded to the scheme used in the GFS model
- Surface momentum and enthalpy flux calculation modified to better match observations
- CO2 transmission coefficient now calculated at run time
- Preliminary development towards optional third moving nest domain capability added
- Preliminary development towards alternate vortex following algorithm added
- Recent bug fixes made to SAS, microphysics, and radiation will make the answer of the community HWRF code differ from the code implemented for 2011 operations at NCEP.
- Vortex initialization algorithm revised with improved storm size correction and improved initial mass-wind balance
- Grid-Point Statistical Interpolation (GSI v2.5) data assimilation capability added
- East Atlantic domain for the ocean component Princeton Ocean Model (POM) added
- Postprocessing upgraded from WPP to Unified Post Processor (UPP)
- Other bug fixes
- The beta release consists of customized versions of the components, HWRF utilities, POM-TC, NCEP Coupler, GFDL Vortex Tracker, WRF, and WPP.
