NOAA has so far completed five flights into and around Hurricane Ida as it crossed over the Cayman Islands and western Cuba toward its forecast landfall along the Louisiana coast. Two synoptic surveillance missions were conducted by the NOAA G-IV high-altitude aircraft to gather dropwindsonde and Doppler radar data around the hurricane to be ingested … Continue reading Flights continue in Hurricane Ida

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

HRD recaps flights into Hurricane Elsa
NOAA conducted six flights into Hurricane Elsa earlier in July, four with the P3s and two with the G-IV. The G-IV operational synoptic flow missions were conducted to gather information from high-levels of the atmosphere around Elsa to improve model forecasts of the storm's track and intensity. The P3 missions were conducted to gather data … Continue reading HRD recaps flights into Hurricane Elsa

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

You can catch Jon Zawislak, Rob Rogers, Joe Cione, and Shirley Murillo talking about hurricanes, or listen in on recordings of panels on coasts and coral reefs, and ocean research, and even a panel … Continue reading AOML holds virtual open house
New study on how energy from the warm ocean fuels hurricanes published in Monthly Weather Review
Summary: The energy that fuels tropical cyclones comes from the heat and moisture in the warm ocean water below. In a classical theory for tropical cyclone intensification, called Wind Induced Surface Heat Exchange or WISHE, an increase in surface wind speed allows for greater energy transfer from the ocean to the atmosphere (Fig. 1a). This … Continue reading New study on how energy from the warm ocean fuels hurricanes published in Monthly Weather Review
