Use of satellite imagery to diagnose events leading to frontal thunderstorms: Part I of a case study

This is the authors' abstract. We don't add key points for this paper.

This paper presents a case study to illustrate the value of water vapour and other satellite imagery, when used in conjunction with a conceptual model, to help the forecaster identify deficiencies in numerical model forecast guidance and to diagnose what is happening on the mesoscale. The specific application discussed is the triggering of frontal thunderstorms by the pattern of overrunning and ascent associated with an upper‐level vortex in the vicinity of a trailing cold front.
