2018 Hurricane Field Program now available

Since 1956, the Hurricane Research Division has carried out an annual field program in which data on Atlantic hurricanes is collected from a variety of platforms, primarily NOAA aircraft.  Since the early 1970s plans for particular experiments were documented prior to the start of the season, to better allocate resources and personnel. This year's plan …

HRD Monthly Science Meeting of June 2018

HRD Seminar – Dr. Andrew Hazelton, NOAA/GFDL, Princeton, NJ – 29 May 2018

Dr. Hazelton presented a seminar titled “High-Resolution fvGFS Forecasts of Atlantic Tropical Cyclones: Structural Analysis and Evaluation of the 2017 Atlantic Hurricane Season”. ABSTRACT: As numerical models reach finer horizontal and vertical resolution, evaluation of storm structure is critical to model assessment and improvement.  Structural metrics based on horizontal wind are examined in high-resolution TC forecasts …

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 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 …

HRD Monthly Science Meeting of April 2018

April’s science meeting consisted of five presentations: Andrew Kren - Impact of Global Hawk dropsonde data assimilated in the NCEP GFS model during SHOUT: Hurricanes Matthew and Nicole in 2016 Hui Christophersen - Impact of Global Hawk Dropsondes on Tropical Cyclone Analyses and Forecasts Sim Aberson -  1-km HEDAS analysis of Hurricane Patricia just after peak …

HRD Monthly Science Meeting of March 2018

March’s science meeting consisted of four presentations: Josh Wadler, UM/RSMAS: Downdrafts and the Evolution of Boundary Layer Thermodynamics in Hurricane Earl (2010) Before and During Rapid Intensification Ghassan Alaka: Evaluation of Track Spread in Hurricane Joaquin (2015) Heather Holbach: Dropsonde Wind Speed Comparison to SFMR at Coyote Flight Levels Kelly Ryan-Poterjoy: Coyote Thermodynamic Verification using …

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 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 …

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 …
