Study on how Hurricane Dorian organized before rapidly intensifying published in Monthly Weather Review

This study showed that a weak, disorganized tropical system in an environment that is not primed for intensification can develop a new center where conditions are more favorable for intensification.  The ability to observe the center of circulation, the tilt of the vortex with height, the depth of the vortex, the wind shear, and locations … Continue reading Study on how Hurricane Dorian organized before rapidly intensifying published in Monthly Weather Review

NOAA completes aircraft investigations into Hurricane Sam

The two NOAA P-3 aircraft, along with the NOAA G-IV, are returning to Lakeland today after 6 days in the Caribbean flying into and around Hurricane Sam, the strongest storm in the Atlantic so far this year. The aim of these collaborative missions between AOML/HRD and the Office of Naval Research Tropical Cyclone Rapid Intensification (TCRI) field … Continue reading NOAA completes aircraft investigations into Hurricane Sam

Hurricane Field Programs gears up to fly Sam, recaps missions so far this year

All three NOAA heavy aircraft are deploying to St. Croix today in preparation for missions into what is now Tropical Storm Sam. AOML/HRD plans to collaborate with the Office of Naval Research Tropical Cyclone Rapid Intensification (TCRI) field campaign to fly P-3 and G-IV aircraft missions into Hurricane Sam in the central North Atlantic. The … Continue reading Hurricane Field Programs gears up to fly Sam, recaps missions so far this year

Flights continue in Hurricane Ida

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

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. While the official hurricane season concludes on November 30, tropical storms may continue to develop past that … Continue reading Record-breaking Atlantic hurricane season draws to an end

Tropical Storm Eta expected to strengthen while AOML supports further reconnaissance

The NOAA Hurricane Hunters resumes missions into Eta on Tuesday, November 10, once their aircraft completed routine maintenance. Hurricane scientists supporting the flights will quality control the data collected from both aircraft such that the appropriate observation coverage and measurements optimize the performance of operational weather models. Tasked by the National Hurricane Center (NHC), the … Continue reading Tropical Storm Eta expected to strengthen while AOML supports further reconnaissance

Tropical Storm Eta evokes multiple taskings to aid in its forecast

NOAA Hurricane Hunters continue reconnaissance an surveillance for Tropical Storm Eta, which threatens to bring tropical-cyclone hazards to south Florida as it restrengthens over water.  The G-IV aircraft took off for its last mission into Eta at 12:30 AM EDT from Lakeland, FL, on November 8. By circumnavigating the periphery of the system, the data supplied hurricane experts … Continue reading Tropical Storm Eta evokes multiple taskings to aid in its forecast

AOML scientists assess the potential for Tropical Storm Eta to intensify

Tasked by the Environmental Modeling Center (EMC) and the National Hurricane Center (NHC), NOAA's P-3 and G-IV aircraft have conducted reconnaissance and surveillance for Tropical Storm Eta. Missions are scheduled to proceed through the weekend. AOML scientists remotely supporting NOAA's G-IV flights continue to provide high-quality data to operational weather models. NHC credits the shift in … Continue reading AOML scientists assess the potential for Tropical Storm Eta to intensify

NOAA Hurricane Hunters set eyes on Tropical Depression Eta

The Environmental Modeling Center (EMC) tasked NOAA's P-3 aircraft to investigate Tropical Depression Eta as the circulation slowly propagates back into the western Caribbean.  The P-3 took off from Lakeland, Florida at 1 PM EDT on November 6 for its 8-hour-long mission into the system. AOML scientists both onboard the aircraft and remotely will process measurements to … Continue reading NOAA Hurricane Hunters set eyes on Tropical Depression Eta
