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, […]
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 […]
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 […]
With the start of the 2018 hurricane season less than two weeks away, HRD and AOML employees have been engaging in several outreach opportunities to promote hurricane preparedness and enhance public understanding of the role of research in improving hurricane forecasts. From May 10th to the 12th, NOAA’s AOML, Southeast Fisheries Science Center, and Miami […]
The webinar was the first in a series of five webinars presented by NOAA’s Southeast and Caribbean Regional Collaboration Team (SECART) in advance of the 2018 Atlantic Hurricane Season by NOAA specialists from the National Hurricane Center (NHC), the Atlantic Oceanographic and Meteorological Laboratory (AOML), the National Weather Service Forecast Offices (WFOs) as they provide […]
The 8th Ensemble Kalman Filter Data Assimilation Workshop was held in Sainte-Adèle, Québec, and HRD scientist Jon Poterjoy chaired a session on Transport problems and non-Gaussian problems and presented “Toward the Application of Particle Filters for Numerical Weather Prediction and Research.” You can follow the link to see the presentation, and other presentations from the workshop.
May’s science meeting consisted of three presentations: Jonathan Zawislak – The Relationship Between Observed Thermodynamic and Precipitation Properties During TC Intensity Change Paul Reasor – Vortex Alignment Processes in Vertically-Sheared Tropical Storms John Kaplan – Statistical Rapid Intensification Model Development: Recent Results and Efforts to Include Storm Structure All the presentations are available on the […]
Summary: Forecasters and researchers use the Hurricane Weather Research and Forecasting (HWRF) model to forecast where a hurricane will go, how strong and large it will be, and where the strongest winds will be. Wind in hurricanes are different over very short distances like 100 m, or the length of a football field, what is […]
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 […]
