## H*Wind JHT Update

- Mark Powell, Sonia Otero, Nirva Morisseau-Leroy, Nick Carrasco, Shirley Murillo, Jason Dunion, George Soukup, Russell St Fleur
- NOAA Hurricane Research Division, AOML

## Assembles all in situ and remote measurement platforms
Common framework: max 1 min wind, 10 m, marine or open exposure, plotted relative to storm
Provides the forecaster with the tools to examine and interact with the observations
Relies on the forecaster’s knowledge and experience to QC the observations 
Objective analysis products designed to visualize windfield at time of warning or advisory
Limitations: dependent on sufficient data coverage, stationarity over 4-6 h, updates required when critical data arrive after analysis time

## Training at TPC: Valuable feedback: Laura Salvador and Rich Knabb: testing and trainingNeed realtime simulation mode for training!
Shirley Murillo and Jason Dunion:  training coordination

## H*Wind designed as a global TC wind field monitoring system:         JTWC beginning to evaluate
Cyclone Kalunde yesterday morning based on QuikScat and ships help define 33kt and 50 kt radii  
Max winds not resolved

## Output Archive

## Code development, User RequirementsTesting in an operational environment Constant feedback and close cooperation with software developersList of prioritized operational requirements based on user experience:User-defined A/C reductions, New GPS sonde WL 150 platform, Autopilot, two GPS-based A/C adjustments, Operational and User Output web archive,        grid data for AWIPS, flag tools (single, by window, and by platform), obs focused on storm, storm center tool, web-based bug reporting system, web-based launching
On track for transition by August 2003...

## Timeline

Remaining Timeline:
April: Complete remaining software enhancements
April: Install H*Wind and test on JHT server 
May: Assist NHC with installation on operational h/w
May: Migrate or replace data procedures and LDM scripts
June-July:  Operational tests of H*Wind on TPC operational system

## Remaining Issues:Domain size:  Need to be able to contain Gulf of Mexico (Isidore)Which Obs are correct?  GPS, Aircraft, SFMR, QScat...     Forecaster’s experience makes the call!                                   Buoy/C-MAN data are critical for validation!Data flow and timeliness: operational status will helpLand data still problematic but exposure info will help (ongoing)Forecaster work load:  Who will do operational analyses?  Answer phones?Products:  Will wind fields become official products?              Who are the users?Need to depict wind direction, probabilistic wind field analyses
