An Algorithm to Identify Robust Convective Weather Avoidance Polygons in En Route Airspace

Abstract

†‡ The paper describes an algorithm for constructing convective weather avoidance polygons. The algorithm combines weather avoidance fields (WAF) from the en route convective weather avoidance model (CWAM) with edges automatically detected in the echo tops field, clustering, convex hull fitting and wind data to build weather avoidance polygons. Results for 2 case days with significantly different weather patterns were classified and studied.
