JTWC Satellite Operations (SATOPS) Capt Kathryn Payne 27 April W SINLAKU ATCF

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

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

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

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

2008 Satellite Fixes By Agency 73% 6% 16% Total Satellite Fixes = 12, %

2008 Geostationary Fixes By Platform (PGTW) Total Geostationary Fixes = 4, % 36% 2%

2008 Microwave Fixes By Platform (PGTW) Total Microwave Fixes = 5,111  Over half of PGTW fixes are now microwave % 17% 13% 7% 9% 15% 5%

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

DOTSTAR Dropsonde DataDOTSTAR Dropsonde Data -Received via 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 nm35-kt wind radii by 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

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
