A TAF Workflow Model Review Satellite Review Num. Pred. SPIN-UP Check model initialization against satellite & obs Uncertainty Review local TAFS Confirm Check specific model fields Decisions Write TAF parameters Submit TAF 11/14/2018 Applied Physics Laboratory
Preliminary Conclusions Heavy reliance on UW MM5 web site Small portion is used most: loops EFS not used, yet Verification of past forecasts not done Concern with model initialization vs. sat & obs Tools at hand does not make this easy Biggest uncertainty for the TAF is whether to stick with model or offset it 11/14/2018 Applied Physics Laboratory
Visualization Improvements What we can’t do Use the “New Paradigm” as a framework for vis. tools Support where uncertainty is largest 11/14/2018 Applied Physics Laboratory
Applied Physics Laboratory Future Work Analysis of current tapes More CTA NWS Additional Navy forecast center Based on CTA develop a prototype interface that includes the verification system & EFS Test of multi-monitors & curved screen (Psych, APL & MS) 11/14/2018 Applied Physics Laboratory
