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.
