Diagnostic Study of a Genesis of Atlantic Lows Experiment (GALE) Cyclogenesis Event.

Abstract

The Navy Operational Regional Atmospheric Prediction System (NORAPS) analysis and forecasts, with 80 km resolution, are used to investigate an explosive cyclogenesis event that occurred in Intensive Observation Period (IOP) 2 during 26-28 January 1986. A synoptic investigations and quasi-Lagrangian diagnostic evalation of the primary cyclone mass, vorticity, heat and moisture budgets are discussed. Explosive developement occurs with the superposition of an upper-level jet streak over a shallow surface system associated with a well developed coastal front. The avection of shear vorticity aloft in combination with warm advection induces strong low-level convergence and spin-up of the low-level vortex. Significant surface sensible and latent heat fluxes and latent heating maxima are closely correlated with the period of rapid development from 00-12 GMT 227 January 1986.
