35th Anniversary of first airborne Doppler radar measurements made in a tropical cyclone

On September 14, 1982, while NOAA42 was flying the first Synoptic Flow experiment, NOAA43 was taking the first Doppler radar readings from an aircraft in a tropical cyclone. The flight into Hurricane Debby was designed to fly several legs into and out of the eye, forming triangular areas where the radar scans would overlap from … Continue reading 35th Anniversary of first airborne Doppler radar measurements made in a tropical cyclone

35th Anniversary of first Synoptic Flow mission

On September 14, 1982, NOAA42 flew the first Synoptic Flow Experiment around Hurricane Debby.  The idea behind the experiment was to fly a large-scale pattern around a hurricane while releasing dropwindsondes at regular intervals.  This would create a three-dimensional map of the winds steering the storm.  The data would be entered into hurricane track forecast … Continue reading 35th Anniversary of first Synoptic Flow mission
