2. Overview Changes since last METSAT Conference SATOPS Mission/Manning Fixing Process/Stats SATOPS Initiatives Challenges

3. TC Recon Network Since the last METSAT Conference…Since the last METSAT Conference… –TC Recon Network disbanded –AFWA (KGWC) ceased fixing responsibilities (2007) –JTWC now has the sole Tropical Cyclone (TC) Reconnaissance Mission in USPACOM –AF Weather support for Mark IVB program suspended, restored

4. SATOPS Mission Support JTWC TC Forecast Operations –METWATCH AOR for disturbances –Evaluate disturbances for TC genesis –Assess TC position/intensity –Synergistic relationship with Typhoon Duty Officers (TDOs) –Post-storm F-deck QC –Transition research to operations through collaboration

7. Fixing Process JAAWIN Position Fix every 3 hours –VIS, IR, Multi-spectral Intensity Estimate every 6 hours –Dvorak Technique Code and Transmit Bulletin Process Other Agencies’ Fixes Radar/Dropsonde fixes Microwave Fixes as available –Now transmitted longline Post-storm F-deck QC –Prior to final best track –After-the-fact fixes –Quality review of fixes –Feedback to analysts

12. AMSU Temperature ProfilesAMSU Temperature Profiles -CIMSS and CIRA websites -Used to classify Subtropical Cyclones, transition of cold to warm core, assess ET, genesis? SATOPS Initiatives

13. DOTSTAR Dropsonde DataDOTSTAR Dropsonde Data -Received via e-mail from Taiwan CWB -Data entered into ATCF -TDO gains valuable data for TC wind field SATOPS Initiatives TC 15W (Sinlaku) Based on DOTSTAR data, TDO increased 35-kt wind radii by 40-45 nm35-kt wind radii by 40-45 nm 50-kt wind radii by 25 nm50-kt wind radii by 25 nm 64-kt wind radii by 20 nm64-kt wind radii by 20 nm

14. SATOPS Initiatives T-PARC 2008 –3-hourly Dvorak fixes –Double Blind SATCON validation (CIMSS) SATCON –CIMSS AMSU, CIRA AMSU, ADT –ADT/MW Microwave Intensity Project –Follow on to work by Edson Quikscat Ambiguities –Reinvigorating training process
