HRD observation team monthly meeting – 16 February 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 … Continue reading HRD observation team monthly meeting – 16 February 2017

HRD scientists participate in HFIP Annual Review, NHC, Miami, FL – 11-12 January 2017

The HFIP program is coordinated through 3 strategic planning teams (Model Development, Data Assimilation/Ensemble, and Post Processing and Verification Development) and 3 tiger teams (High Resolution Physics, Ensemble Product, and Ocean Model Impact). The HFIP strategic planning teams develop our multi-year strategy for improving hurricane forecast guidance, while the tiger teams are responsible for overseeing … Continue reading HRD scientists participate in HFIP Annual Review, NHC, Miami, FL – 11-12 January 2017

2016 Hurricane Season ends

Today marks the last day of the 2016 Atlantic hurricane season, and it was a busy one for us.  AOML's Hurricane Research Division (HRD) participated in 57 missions into six different tropical cyclones: Colin, Earl, Javier (East Pacific), Hermine, Karl, and Matthew.  From early June to the start of October, HRD personnel either flew on-board … Continue reading 2016 Hurricane Season ends

HRD Seminar – Dr. Chris Hennon and Will Clark, University of North Carolina at Asheville – 11 October 2016

Dr. Hennon presented a seminar on “Toward a Global Homogeneous Tropical Cyclone Data Record". Abstract Any analysis of global tropical cyclone (TC) activity must account for the myriad of interagency differences in determining maximum wind speed.  Although the use of the Dvorak technique is the dominating factor in the vast majority of all agency estimates, … Continue reading HRD Seminar – Dr. Chris Hennon and Will Clark, University of North Carolina at Asheville – 11 October 2016

HRD Debrief for missions into Hurricane Hermine – 15 September 2016

HRD researchers discussed the results from the 11 P-3 missions into AL99, TD9, and eventually Hurricane Hermine (25 August to 2 September 2016).
