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 …

Paper on the impact of dropwindsondes from the Global Hawk on forecasts released online in Monthly Weather Review

Summary:  A drone, what we call an unmanned aircraft system, can collect data in tropical cyclones (TCs) to improve forecasts.  Scientists have used the Global Hawk drone that can fly at an altitude of up to 60,000 feet for over 24 hours at a time since 2010. The Global Hawk releases dropwindsondes that measure wind, …

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 …
