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

H*Wind • 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 Receiving training Laura Salvador Alison Krautkramer Jorge Aguirre Robbie Berg Eric Blake Dan Brown Chris Burr Hugh Cobb James Franklin Eric Holweg Richard Knabb Miles Lawrence Rob Molleda Martin Nelson Richard Pasch Stacy Stewart

• H*Wind designed as a global TC wind field monitoring system: JTWC beginning to evaluate • Cyclone Kalunde yesterday morning based on Quik. Scat and ships help define 33 kt and 50 kt radii • Max winds not resolved • Greg Send Aerosondes!!!

• • WMO Course: Trained 18 forecasters from St. Lucia, Neth. Antilles, Thailand, Dominican Republic, Guadeloupe, Antigua, Jamaica, Cuba, Trinidad and Tobago, Martinique, Grenada, Korea, China, Singapore, Costa Rica, Phillipines, Venezuela, Bahamas, Bermuda, Canada COMET Mesoscale Analysis and Prediction course in Boulder June 2002 (SOO training) Many enthusiastic about using H*Wind. Short movie available.

• Users guide and glossary available on web for additional training and reference • Leads the user through all steps of conducting realtime analysis

• • • Output displayed on NHC Intranet 104 Realtime Analyses Atlantic al 03 Cristobal 3 al 05 Edward 6 al 08 Gustav 11 al 09 Hanna 6 al 10 Isidore 24 al 12 Kyle 4 al 13 Lili 36 al 14 TD 14 4 al 95 Invest 1 Pacific ep 05 Boris 1 ep 06 Elida 2 ep 07 Noname 2 ep 14 Kenna 4 wp 09 Rammagun 1 wp 10 Halong 1

• 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
