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
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

Thirty-one AOML and HRD scientists participated in the recent 33rd AMS Conference on Hurricanes and Tropical Meteorology in Ponte Vedra, FL, as authors or co-authors on 65 presentations and 19 posters. Roughly 783 presentations (507 oral presentations in 67 sessions and 276 posters in 2 session) were submitted to the conference. Of the 567 TC-related presentations … Continue reading AOML and HRD researchers at 33rd AMS Conference on Hurricanes and Tropical Meteorology, Ponte Vedra, FL – 15-20 April 2018
May’s science meeting consisted of three presentations: Jonathan Zawislak - The Relationship Between Observed Thermodynamic and Precipitation Properties During TC Intensity Change Paul Reasor - Vortex Alignment Processes in Vertically-Sheared Tropical Storms John Kaplan - Statistical Rapid Intensification Model Development: Recent Results and Efforts to Include Storm Structure All the presentations are available on the … Continue reading HRD Monthly Science Meeting of May 2018
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
AOML's Diversity, Inclusion & You (DIY) group honored employees who went above-and-beyond their regular duty during Hurricane Irma's impact on their homes and families last September. Among those honored were a number of HRD employees: Jonathan A. Zawislak, Bradley W. Klotz, Heather M. Holbach, Lisa R. Bucci: For exceptional professionalism and dedication to NOAA’s mission, … Continue reading HRD employees honored with Andrew Awards for going above-and-beyond during Hurricane Irma
Abstracts and recordings of the 27 presentations and 9 posters AOML & HRD researchers presented (or were co-authors) at the 98th AMS Annual Meeting are available online from the AMS website: Presentations: Karina Apodaca, M. Zupanski, L. Cucurull, and M. Hu - Implementation of the GOES-16 GLM Lightning Assimilation into the NCEP/GSI System for Improved … Continue reading HRD & AOML researchers at 98th American Meteorological Society Annual Meeting, Austin, TX – 7-11 January 2018
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
