AOML and HRD researchers at 33rd AMS Conference on Hurricanes and Tropical Meteorology, Ponte Vedra, FL – 15-20 April 2018
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 …
Paper on how small-scale changes in winds in hurricanes impact hurricane forecasts published in Weather and Forecasting
Summary: Forecasters and researchers use the Hurricane Weather Research and Forecasting (HWRF) model to forecast where a hurricane will go, how strong and large it will be, and where the strongest winds will be. Wind in hurricanes are different over very short distances like 100 m, or the length of a football field, what is …
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 …
Best Student Poster at AMS 33rd Hurricane Conference
The Best Student Poster for Mesoscale Meteorology Award at the AMS 33rd Hurricane and Tropical Meteorology Conference was awarded to University of Utah student George (Trey) Alvey III and co-authored by HRD's Rob Rogers and Jon Zawislak along with U. Utah Professor Ed Zipser. The poster was titled "Hurricane Edouard's (2014) Intensification: The Relationship between …

NOAA Hurricane Research overview for WMO Region IV Training Workshop, NHC – 26 February 2018
To demonstrate how tropical cyclone research is used to improve forecast guidance HRD researchers Drs. Frank Marks, Robert Rogers, and Jason Sippel presented summaries of “NOAA’s Hurricane Research”, “Aircraft Observations of Tropical Cyclones”, and "Tropical Cyclone Modeling and Data Assimilation" to the World Meteorological Organization Regional Association IV Training Workshop held in the National Hurricane …
HRD & AOML researchers at 98th American Meteorological Society Annual Meeting, Austin, TX – 7-11 January 2018
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 …
HRD Monthly Science Meeting of February 2018
February’s science meeting consisted of three presentations: Rob Rogers: The relationship between tropical cyclone structure and intensification in moderate vertical shear Jon Zawislak: 2018 NOAA/AOML/HRD Hurricane Field Program Intensity Forecast Experiment (IFEX): Overview of Experiment Design Pete Black: Emerging Airborne Technologies for improved TC Track and Intensity Forecasting: Preliminary Observations from SHOUT and EPOCH All the …

Paper on the difference between rapidly intensifying storms and those that don’t intensify as fast published in Journal of the Atmospheric Sciences
Summary: The main model that forecasters use to predict what a hurricane will do is the Hurricane Weather Research and Forecast (HWRF) model. Because we cannot measure what is currently happening in the hurricane exactly, we run the model many times at once with different measurements to get an idea of the different forecasts that …
NOAA flights into 2017 major hurricanes, improvements to HWRF and the basin-scale model, recalling Hurricane Andrew, and a tribute to Mike Black in the most recent version of AOML Keynotes
