HRD Seminar – Dr. Morgan O’Neill, T. C. Chamberlin Postdoctoral Fellow, University of Chicago – 14 November 2017

Dr. O'Neill presented a seminar on “Diurnal gravity waves as a probe of hurricanes’ internal structure“. Abstract: Satellite observations of cloudy hurricane canopies have shown a universal, daily, wave-like feature that propagates radially outward, as far as 600 km (Dunion et al. 2014). Daytime solar heating of a hurricane’s upper eyewall is surely responsible, but …

Paper on the difference between rapidly intensifying storms and those that don’t intensify as fast released online 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 …

HRD observation team monthly meeting – 16 November 2017

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 …

Paper on a way to initialize idealized hurricane models published 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 …

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 …

Shirley Murillo elected to the American Meteorological Society Council

Shirley Murillo has won election to the Council of the American Meteorological Society as representative from the Government Sector.  The Council is the principal governing body of the Society.  It consists of the elective officers, the last two Past-Presidents, and 15 other voting members of the Society, each elected for a three-year term, with one-third …

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 …
