Abstract

Abstract : Analysis of moist airflows associated with a case study, storm Bronagh, is conducted to determine whether moisture contributing to observed precipitation near the cyclone centre is transported from the subtropics or local environment. Reanalysis data are used to identify the warm conveyor belt and dry intrusion, and an algorithm is developed to identify the presence of the feeder air stream (FA) during the storm's evolution. We conclude that during the intensification stage, moisture is transported by the FA from the local environment into which Bronagh is propagating and not from the reservoir of moist air in the subtropics.
