New study on how changes in ocean temperature near the coast during landfall can intensify hurricanes released online 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 changes in ocean temperature near the coast during landfall can intensify hurricanes released online 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

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

Record-breaking Atlantic hurricane season draws to an end

Improved forecasts, extensive preparedness helped protect lives and property From https://www.noaa.gov/media-release/record-breaking-atlantic-hurricane-season-draws-to-end. The extremely active 2020 Atlantic hurricane season is drawing to a close with a record-breaking 30 named storms and 12 landfalling storms in the continental United States.

Hurricane Delta Slowly Weakens prior to landfall on the Louisiana Coast

AOML scientists observed the slow weakening of Hurricane Delta during the last NOAA P-3 Hurricane Hunter mission, tasked by the Environmental Modeling Center (EMC) on the morning of October 9.  Delta's minimum central pressure gradually rose and surface wind speeds measured by the Stepped-Frequency Microwave Radiometer (SFMR) steadily lowered throughout the mission. Time series of (top) SFMR wind … Continue reading Hurricane Delta Slowly Weakens prior to landfall on the Louisiana Coast

NOAA Hurricane Hunters conduct final mission before Hurricane Delta’s landfall

NOAA concludes Environmental Modeling Center (EMC) tasked reconnaissance for Major Hurricane Delta on October 9. The P-3 aircraft took off from Lakeland, FL, at 5:00 AM EDT to survey the system's circulation. With the P-3 passing through the center multiple times, AOML scientists onboard and remotely supporting the missions continue to evaluate data collected from … Continue reading NOAA Hurricane Hunters conduct final mission before Hurricane Delta’s landfall
