## Getting Behind The TAF

- Kris Kimmons
- Continental Airlines

## Aviation User’s View Of Weathermen & The Weather

## Cloaked In Your CAPEs & Lurking Behind A Theta-E Ridge

## TAF Offers Limited Information

- Covers 5 mile radius
- Does not convey forecaster confidence
- Low Visibility
- What Does VCTS “Really” Mean?
- Aviation Users Decidedly Deterministic
- “Gap” Between TAFs & Mesoscale Products

## Using The AFD In Aviation Planning

- Addresses Forecaster Confidence
- Addresses Problems Outside Of TAF Radius
- Gives Users Better Understanding Of Forecast Process
