Paper on updrafts in hurricanes and how they relate to intensity changes published in Monthly Weather Review

Summary:  NOAA Hurricane Hunter aircraft have a Doppler radar that measures wind through the entire hurricane.  We analyzed these radar data collected in many hurricanes since 2004.  Previous studies found that the location of the fastest upward moving air (what we call updrafts) may tell us how strong the storm will be a few hours …
