Real-time guidance provided by NOAA's hurricane research division to forecasters during Emily of 1993

Abstract

The Hurricane Research Division (HRD) is NOAA's primary component for research on tropical cylcones. During the 1993 hurricane season, HRD demonstrated three important real-time capabilities for the first time. These achievements included the successful transmission of a series of color radar reflectivity images from the NOAA research aircraft to NHC, the operational availability of objective mesoscale streamline and isotach analysis of a hurricane surface wind field, and the transition of the experimental dropwindsonde program on the periphery of hurricanes to a technology capable of supporting operational requirements. Examples of these and otehr real-time capabilities are presented for Hurricane Emily (1993). -from Authors
