Future of Satellites- Conclusions JTWC needs assistance in quantifying satellite platforms’ impact to operations –Ex: reduction in forecast errors, $ saved, sorties prevented JTWC needs a systematic way to advocate for satellite programs (ex. GCOM scatterometer/AMSRE) A temporal sampling requirement is needed for microwave imagery/sounders –Ex: imagery needed every 3 hours Request increased resolution for MIS (NPOESS) sensor

Quikscat Essential to JTWC operations –Synoptic Analysis –Initial warnings often based on quikscat winds Windsat/ASCAT- poorer spatial resolution First scheduled replacement- Dual Frequency Scatterometer (DFS) 2016 Potential to run second ASCAT 20 minutes after 1 st –ASCAT flies on MetOp series Quikscat Windsat Ascat

Dvorak Technique Due to lack of aircraft recon, Dvorak primary tool for intensity estimates Known weaknesses in Dvorak present problems for TDO/analyst –Few updates to process in 30 years –Subjectivity –Rapid intensification –Weakening systems –Weak, developing systems –Midgets/pinhole eye

Improvements to Intensity Estimates Need correct baseline intensity to improve intensity forecasting Investigate use of CIMSS’ SATCON (Satellite Consensus) intensity estimate as a supplement to Dvorak –Weighted consensus of 3 automated satellite intensity estimates ADT (Advanced Dvorak Technique) AMSU (CIMSS) AMSU (CIRA) –Collaborate to improve understanding of these intensity estimates Priority for improvements concern storms less that 35 kts and rapid intensifiers
