On 16 August, 1977, a tropical wave moved off the coast of Africa. It wasn’t until nearly two weeks later that the wave developed enough convection and a surface circulation, and was designated a tropical depression in the middle of the Gulf of Mexico. The system slowly moved west-southwestward, but rapidly intensifying into a category-5 […]

On 24 August, a tropical wave moved westward off the African coast, gradually becoming organized enough to become a tropical depression a week later almost 200 n mi east southeast of Barbados. Within 12 h, it became Tropical Storm Felix about 60 n mi south of Barbados. A period of rapid intensification commenced, and Felix […]
In the early morning hours of August 24, 1992, Category-Five Hurricane Andrew roared across southern Florida leaving behind a trail of devastation that stunned the nation. Andrew was the first hurricane of this ferocity to hit the continental United States since Hurricane Camille in 1969, and repercussions of its landfall were felt in the world […]
Summary: Sometimes, the wind at the surface around a hurricane is the same around the storm center (what we call a symmetric pattern), and at other times, it is different (what we call an asymmetric pattern). In addition, sometimes the wind pattern stays the same, and sometimes it changes quickly. This study looks at how […]
If you use HRD’s data, NOAA/AOML’s Hurricane Research Division (HRD) invites feedback on your experiences obtaining and using data sets provided by HRD (a list of available products can be found at http://www.aoml.noaa.gov/hrd/data_sub/products.html). We value your time in filling out this important survey, as it will provide critical guidance for HRD scientists as we seek […]
Intensity Forecast Experiment (IFEX) Program Director Paul Reasor and HRD Director Frank Marks briefed the Aircraft Operations Center (AOC) personnel at their brand new facility at Lakeland Linder Regional Airport on IFEX plans for 2017 and Hurricane Forecast Improvement Project progress, respectively. The two presentations are available in a .zip archive on the anonymous ftp […]
July’s science meeting consisted of 6 presentations: Steve Guimond (NASA) – “Reviving the Imaging Wind and Rain Airborne Profiler (IWRAP) for Hurricane Research: A Case Study of Hurricane Rita (2005)” Mu-Chieh (Laura) Ko – “Preliminary Review – HWRF-B 2016 Retrospective Dataset” Robert Rogers – “The Challenge of Intensity Forecasting in Moderate Shear” Emily Paltz (Hollings […]
The Hurricane Weather Research and Forecasting Model (HWRF) has become an important tool for both hurricane forecasters and researchers. The current HWRF has three domains around only one tropical cyclone. Its inner domain makes forecasts on a grid with points 2 km apart and follows the tropical cyclone during the forecast. During hurricane season in […]
May’s science meeting consisted of 3 presentations: Jonathan Zawislak: Validation of tropical cyclone precipitation in HWRF using satellite observations Hua Chen – Azimuthal distribution of deep convection, environmental factors, and tropical cyclone rapid intensification: A perspective from HWRF ensemble forecasts of Hurricane Edouard Stephanie Stevenson (University of Albany/SUNY): Understanding intensity changes signaled by tropical cyclone lightning […]
The presentation was the first in a series of three webinars presented by NOAA’s Southeast and Caribbean Regional Collaboration Team (SECART) in advance of the 2017 Atlantic Hurricane Season by NOAA specialists from the National Hurricane Center (NHC), the Atlantic Oceanographic and Meteorological Laboratory (AOML), the Weather Prediction Center (WPC), the Southeast River Forecast Center […]
