NOAA Hurricane Hunters fly into and around Fred, Grace, and Henri, and gear up for the next system

NOAA Hurricane Hunters completed 6 missions into Tropical Storm Fred, and 11 and 7 missions in and around Hurricanes Grace and Henri, respectively. The first mission into Fred occurred before the system had a well-defined center and was not yet named a tropical depression. Subsequent missions sampled the dry air and wind shear around Fred … Continue reading NOAA Hurricane Hunters fly into and around Fred, Grace, and Henri, and gear up for the next system

Jun Zhang participates in 2nd Boundary Layer Workshop

The 2nd Boundary Layer Workshop was held virtually on 1-2 June. The goal of the workshop is to continue the work from the previous one to improve our understanding and modeling of surface and atmospheric boundary layer processes. The event was organized by Tilden Meyers of NOAA's Air Resource's Laboratory and David Turner of NOAA's … Continue reading Jun Zhang participates in 2nd Boundary Layer Workshop

Rob Rogers participates in the 2020 HIWeather Workshop

HIWeather is a World Meteorological Organisation research project, developing warning capabilities for weather-related hazards, to increase resilience worldwide. HIWeather participants form an international network of scientists, in a wide variety of disciplines, all concerned with aspects of the production and communication of weather-related warnings.  The workshop is aimed at anyone interested in improving weather-related warnings, … Continue reading Rob Rogers participates in the 2020 HIWeather Workshop

Paper on the rapid intensification of Hurricane Michael published in Monthly Weather Review

Summary: The energy for tropical cyclones comes mainly from the warm ocean below them.  The warmer the water, the greater the energy, and the easier it is to transfer that energy (heat and moisture) into the air and into the tropical cyclone, allowing the thunderstorms that sustain the cyclone to develop.  Cool water (below about … Continue reading Paper on the rapid intensification of Hurricane Michael published in Monthly Weather Review

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

Hurricane Field Program Update — Friday, August 29, 2019, 7pm EDT

We remain very busy with Hurricane Dorian.   NOAA42 is currently conducting a NHC- and EMC-tasked reconnaissance flight into Dorian.  On their first pass, they found that Dorian was rapidly intensifying and now had a minimum central pressure of 951 mb from dropsonde, and the stepped-frequency microwave radiometer reported surface wind speed of 112 kt … Continue reading Hurricane Field Program Update — Friday, August 29, 2019, 7pm EDT
