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 …

HRD/NHC CHART Seminar – John Kaplan, AOML/HRD – 16 May 2016

John Kaplan presented a seminar on “Investigating the variability in skill of operational statistical rapid intensification (RI) prediction models” that is available on the NHC science presentation web site. Abstract Despite recent improvements in tropical cyclone (TC) intensity forecasting skill, predicting changes in TC intensity remains problematic particularly the forecasting of episodes of rapid intensification …
