2.

3. Motivation/Justification • Supports NOAA Mission Goal(s): Weather and Water • Improved intensity forecasting identified as high priority in NOAA and NCEP/TPC • Intensity forecast skill still lags that of track forecasting • Unanticipated rapid intensity changes are a major problem for coastal evacuations • TC genesis forecasting capabilities are very limited • TC structure analysis can help compensate for loss of scatterometers • Addresses AWG request for more studies of ABI and polar data synergy
4. Methodology • Intensity Forecasting • SHIPS model statistically combines satellite, SST and model output • Evaluate predictive signal of ABI from MSG data • Use AWG tool for combining MSG channels to simulate ABI • Test predictive signal of WWLLN (lightning) data relative to other available information • Stratify by storm environment • Take similar approach with Rapid Intensity Index • Look for precursors to rapid intensification (cloud top signatures, lightning patterns) • Genesis forecasting • Develop experimental version of operational NESDIS TC genesis product • Test proxy ABI and lightning data • Upper level effects of ozone channel • Tropical Cyclone Structure Analysis • Eye soundings using AIRS, IASI retrievals • Wind diagnosis from temperature and moisture profiles (AIRS, IASI, COSMIC) using nonlinear balance equation • Additional tests with synthetic ABI/sounder data from models • Synergistic approach with high/low vertical/temporal polar data and low/high vertical/temporal GOES data
5. Summary of Previous Results • Proxy ABI datasets collected from MSG under previous GOES-R project • Mechanisms developed for creating synthetic ABI data from mesoscale and radiative transfer models • Large IR ABI tropical cyclone datasets collected for AWG project • Mass storage and computer cluster obtained from previous project • Preliminary analysis of ABI channels for storms from 2006 hurricane season • Hurricane eye sounding procedure developed under previous project

7. Major Milestones • FY08 • Assemble proxy lightning mapper, ABI and sounding databases • Modify SHIPS, Rapid Intensity Index, TC genesis parameter to use GOES-R inputs • Test eye sounding technique on large sample of cases • Present preliminary results at AMS tropical conference
Assemble proxy lightning mapper, ABI and sounding databases • The collection of MSG data in the tropical Atlantic for use as proxy ABI data continues using an automated procedure • Algorithm to create simulated ABI channels (7-16) from MSG data • Note: the collection of soundings from the AMSU instrument has long been automated for global tropical cyclones • The AIRS sounding database via the AIRS science team for historical storms has also completed • COSMIC Soundings have been collected from NCAR • The analysis of the World Wide Lightning Location Network (WWLLN) data (2003-2007) continues • comparison with the global lightning climatology from the TRMM mission in 50km X 50km bins • Work has begun to develop a IASI sounding database

Modify SHIPS, Rapid Intensity Index, TC genesis parameter to use GOES-R inputs • The developmental code of these statistical forecast model algorithms have been adapted to utilize satellite data in McIDAS format. • Current GOES/POES • ABI proxy data • simulated ABI channels • Primary emphasis in 2008 is on using WWLLN data in SHIPS intensity forecast model
Calibration of WWLLN Data • WWLLN data available from Aug 2003-Dec 2007 • Calculate lightning density (strikes/km2-year) • Compare with 1995-2005 OTD/LIS climatology OTD/LIS (0.5 deg) Scaled WWLLN (0.5 deg) Average Scale Factor = 57
Cumulative PDFs of the simulated ABI and GOES-E data over the overlap area in the eastern Atlantic 6.7um 6.95um Calibrate geostationary water vapor data to GOES-E is accomplished using the pdf-based method discussed/developed in Kidder, S.Q., and A.S. Jones (2007). In this manner data from all Geostationary platforms, including GOES-R can be easily used in the tropical cyclone formation product or other algorithms. This methodology is also easily applied to any closely related satellite channel/wavelength.
