HRD observation team monthly meeting – 16 August 2018

The purpose of the observation team meetings is to bring together the people who use observations in their research on a regular basis to discuss issues they’re having, provide updates on observations they’re analyzing or collecting, and any other information that may be of interest to the broader group.  These meetings are also an excellent … Continue reading HRD observation team monthly meeting – 16 August 2018

Paper on how eyewall replacement cycles start published in The Journal of the Atmospheric Sciences

Summary: When hurricanes become strong, they sometimes form a second eyewall around the main eyewall. This second ring of strong winds and heavy rain means that strong, damaging winds could cover a larger area than before. However, it also means that the storm might temporarily weaken. Understanding and predicting this process is therefore very important. … Continue reading Paper on how eyewall replacement cycles start published in The Journal of the Atmospheric Sciences

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

Paper on how tropical storms do (or don’t) organize thunderstorms around the center to intensify published in Monthly Weather Review

It has been believed that tropical cyclones are likely to strengthen when strong thunderstorms (called convection) almost completely surround the storm's center. In order to better understand what prevents this convection from surrounding the storm’s center in some storms (but not others), this study analyzes data collected on NOAA aircraft flights in two storms that … Continue reading Paper on how tropical storms do (or don’t) organize thunderstorms around the center to intensify published in Monthly Weather Review
