HRD kicks off 2021 Hurricane Field Program

Scientists from AOML and other agencies participating in NOAA's 2021 Hurricane Field Program's Advancing the Prediction of Hurricanes Experiment (APHEX) met on 26 May to kick off the season. APHEX was developed in partnership with NOAA’s Environmental Modeling Center, National Hurricane Center, Aircraft Operations Center, and AOML’s Physical Oceanography Division. It is intended to improve … Continue reading HRD kicks off 2021 Hurricane Field Program

HRD scientists participate in the 34th American Meteorological Society Conference on Hurricanes and Tropical Meteorology

34th Conference on Hurricanes and Tropical Meteorology Virtual Meeting The 34th AMS Conference on Hurricanes and Tropical Meteorology was held virtually 10-14 May after being postponed from 2020.

Paper that reviews what we know about intensity change published in Atmosphere

This paper is an overview of what we currently know about processes important in tropical cyclone intensity change and the research that has been done during the past 15 years using aircraft data. The paper describes the eye and eyewall and how they change in time, the region close to the ocean surface where the … Continue reading Paper that reviews what we know about intensity change published in Atmosphere

HRD Monthly Science Meeting of April 2021

April's science meeting consisted of four presentations: Xiaomin Chen: "Boundary Layer Recovery and Precipitation Symmetrization Preceding Rapid Intensification of Tropical Cyclones under Shear" Andy Hazelton: "HAFS Ensemble of Hurricane Dorian (2019): Early Intensity and Long-Term Track" Jon Zawislak: "Accomplishments of NOAA's Airborne Hurricane Field Program and a Broader Future Approach to Forecast Improvement" Kathryn Sellwood: … Continue reading HRD Monthly Science Meeting of April 2021

Paper looking at how model forecasts of what is happening near the ocean surface in tropical cyclones changes as the space between forecast points gets smaller was released online in Monthly Weather Review

The energy that fuels tropical cyclones comes from heat and moisture from the warm ocean below.  This energy is transferred from the ocean to the atmosphere and the momentum is transported from atmosphere to surface by what we call turbulent processes in the atmosphere near the ocean surface (what we call the planetary boundary layer … Continue reading Paper looking at how model forecasts of what is happening near the ocean surface in tropical cyclones changes as the space between forecast points gets smaller was released online in Monthly Weather Review

HRD Monthly Science Meeting of March 2021

March's science meeting consisted of three presentations. Michael Fischer: "How are TC convective and vortex characteristics related to TC intensity?" Josh Wadler: "The Effects of Environmental Wind Shear Direction on Tropical Cyclone Boundary Layer Thermodynamics and Intensity Change from Multiple Observational Datasets" Lew Gramer:  “Coastal downwelling and landfalling hurricane intensification” Copies of the three presentations are available … Continue reading HRD Monthly Science Meeting of March 2021

HRD Seminar – Dr. Forrest Masters (University of Florida) – 17 March 2021

Dr. Masters presented a seminar titled "Collecting surface wind and water data in extreme hydrodynamic conditions during tropical cyclone landfall: The Sentinel Project". ABSTRACT: The presentation will describe a new effort to measure surface wind, hydrodynamic, erosion, and water quality conditions in the hurricane core at the coastal transition. In this region, storm surge and … Continue reading HRD Seminar – Dr. Forrest Masters (University of Florida) – 17 March 2021

HRD Monthly Science Meeting of February 2021

February's science meeting was hosted by NHC and consisted of nine presentations. The first two presented an overview of the proposed Tropical Marine Testbed (TMT) from a NWS and OAR perspective, and the remaining seven presentations were from NHC and HRD researchers describing potential projects that the TMT might tackle:  Overview of Tropical Marine Testbed … Continue reading HRD Monthly Science Meeting of February 2021
