NWA’s Implemented Initiatives
• Turbulence Plot System (TPS)
– Convective Wind Shear Alerts
• Strategic Planning Team (SPT)
– Collaborative Convective Fcst Prod (CCFP)

Convective Wind Shear Alerts
• Source– FAA TWIP System
• Distribution Methods
– Pilot Request
– Unsolicited Uplink (Send/Cancel Msgs)
Pt: Addressed Varied Operating Philosophies

Bogus Alerts
• NWA Study Jan-May 2000
– 72 Bogus Alerts - No Storms within 15nm
(25 ranged 50-95kts)
(22 ranged 30-50 kts due gusty winds)
– 100’s Bogus Alerts - No Storms within 15nm
(100’s ranged 20-25kts due gusty winds)
Convective Wind Shear Alerts

Support, Resources and Gaps
• Real time Quality Control
• Conceptual Models
– Convection Induced Shear
– “No Storms within 15nm” Induced Shear
• Training

CCFP
• Excellent Example
– “Rapid Development”
– “User Driven”

CCFP Support, Resourcesand Gaps
• NWA Role
– Industry Perception
– AWC Issues
• Meteorologist Role
– CWSU’s
– Airline Meteorology Offices
• FAA and SPT Role

Summary
• Design Requirement
– Adaptable to varied users
• Recipe for Success
– User Driven Specs
• Potential for Failure– Lack of on going quality control– No Conceptual Model Updating– No Recurrent Training
