2017 Hurricane Field Program summary

AOML's Hurricane Research Division (HRD) ran its 2017 Hurricane Field Program from July 27th through October 27th and accomplished many of the objectives set for this busy hurricane season.  In addition to carrying out Tail Doppler Radar (TDR) missions in coordination with NOAA's Environmental Modeling Center (EMC), HRD flew the Analysis of Intensification Processes Experiments …

Paper on a way to initialize idealized hurricane models released online in the Journal of Advances in Modeling Earth Systems

Computer models developed to forecast the weather need to know what is currently happening in the atmosphere and in the ocean, what we call “initial conditions,” each time the model starts. The process of making these initial conditions is known as “initialization.” This study is about a new initialization method for both the atmosphere and …

10th Anniversary of Aerosonde flying into hurricane-force winds

On November 2, 2007, an unmanned aerial vehicle (UAV) Aerosonde flew into Tropical Storm Noel.  This marks the first time a UAV flew into an Atlantic tropical cyclone while encountering hurricane-force winds. The flying probe was produced by the Australian-based Aerosonde Pty Ltd. (now Textron Systems) which had been manufacturing sensors since 1995.  It reached …

Paper on Hurricane Patricia, the most intense hurricane ever recorded in the Western Hemisphere, published in the Bulletin of the American Meteorological Society

In October 2015, off the west coast of Mexico, Hurricane Patricia became the strongest hurricane ever recorded in the western hemisphere, intensifying faster than any other storm on record. A unique set of observations were collected in Patricia. National Oceanic and Atmospheric Administration (NOAA) and National Aeronautics and Space Administration/Office of Naval Research (ONR) aircraft …

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 …
