1 Update on the Status of Numerical Weather Prediction

2 Panel Overview Numerical Weather Prediction (NWP) is the basis for most forecasts Will provide an update on advances Future NOAA plans Industry trends and capabilities Q&A

3 NWP Advances 40 km grid spacing in 1998 3 km grid spacing in 2014
240 km/150 mi

4 Convective Forecasts Comparison Then vs. Now
Observation Then Now

5 Ensembles for aviation are coming
A collection of numerical weather forecasts Ensembles are not new Why use? Gives a range of scenarios that may occur Gives confidence in a particular solution Measure of uncertainty Can produce probabilities Can be applied to risk-based decision making

6 How can one use multiple forecasts?

7 Why not just use the Mean?
According to the Mean, one might feel pretty good

8 Questions to Ponder What grid spacing and resolution is needed?
Is the aviation user community ready for ensembles? What is the role of NWP for human decision makers? Are decision support tools ready for ensembles?
