Recap of Julia and Lisa flights

NOAA conducted two flights into Julia and five into Lisa during October of this year, all in the Caribbean Sea. The main purpose of all the missions was to gather Doppler Radar and dropwindsonde data for ingestion into NOAA's computer models to improve forecasts. Flight tracks of missions into Julia (left) and Lisa (right) during … Continue reading Recap of Julia and Lisa flights

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

Review of aircraft missions into Hurricane Earl

NOAA conducted 20 aircraft missions into Hurricane Earl in late August and early September. The series of flights over 12 days was the longest series of flights into one system that NOAA has conducted. We recently reviewed these flights, and the slides from the review can be found here. Flight tracks of all the NOAA … Continue reading Review of aircraft missions into Hurricane Earl

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

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
