Recap of Hurricane Ian flights

In September, NOAA conducted 15 missions in and around Hurricane Ian before its historic landfall in Florida. Among these were 8 P-3 missions and 7 synoptic surveillance missions conducted by the G-IV. One hundred forty-three dropwindsondes were released along with 18 Airborne Expendable Bathythermographs to measure profiles in the atmosphere and the ocean underneath Ian. … Continue reading Recap of Hurricane Ian flights

Frank Marks participates in Symposium on Tropical Cyclones, Convection and Climate – 21-22 June 2022

Kerry Emanuel has made fundamental contributions to several areas in the study of Earth's climate, notably related to tropical cyclones, convection, and climate. This two-day symposium in honor of Kerry Emanuel brought current work across these three areas together in one place, and provided a forum for exchange of ideas at current forefronts in these … Continue reading Frank Marks participates in Symposium on Tropical Cyclones, Convection and Climate – 21-22 June 2022

Article on wind and turbulence near the surface in landfalling tropical cyclones published in Nature Scientific Reports

This study examines the structure of the part of the atmosphere closest to the surface in a landfalling tropical cyclone (TC) using land-based tower observations. Turbulence is made up of random and continuously changing wind that mixes the atmosphere allowing the energy from the warm ocean below to move upward and fuel the hurricane.  Observations … Continue reading Article on wind and turbulence near the surface in landfalling tropical cyclones published in Nature Scientific Reports

NOAA Hurricane Field Program begins with flights into Potential Tropical Cyclone 2 in the Tropical Atlantic

The NOAA flight season began early this year with an operational flight into a system, known as Potential Tropical Cyclone 2, that may soon develop into a tropical depression east of the Windward Islands. The plan for the season was recently released and is available online at https://www.aoml.noaa.gov/2022-hurricane-field-program/, and a kickoff meeting to discuss plans … Continue reading NOAA Hurricane Field Program begins with flights into Potential Tropical Cyclone 2 in the Tropical Atlantic

New study on how landfalling hurricanes can change ocean temperatures near the coast causing the hurricane to intensify published in Geophysical Research Letters

This study uses a state-of-the-art hurricane modeling system developed at the NOAA/Atlantic Oceanographic and Meteorological Laboratory’s Hurricane Research Division, the Basin-Scale Hurricane Weather Research and Forecast (HWRF-B) model, to demonstrate a link between an oceanographic process called coastal downwelling and the intensification of tropical cyclones (TCs or hurricanes) near landfall. We show that coastal downwelling … Continue reading New study on how landfalling hurricanes can change ocean temperatures near the coast causing the hurricane to intensify published in Geophysical Research Letters

Study on the impact of mountains on rainfall and intensity of tropical cyclones published in Monthly Weather Review

This paper explores the effect of mountainous terrain on the structure of a tropical cyclone eyewall by using a numerical model to simulate the landfall of a typhoon in the Central Mountain Range (CMR) of Taiwan and its reemergence over water after crossing the CMR. It was found that the presence of the CMR disrupted … Continue reading Study on the impact of mountains on rainfall and intensity of tropical cyclones published in Monthly Weather Review
