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

Hurricane and Ocean Testbed Technical Workshop

NOAA P-3 data and satellite imagery overlain during a mission into Lisa. Data from the Imaging Wind and Rain Airborne Profiler (showing wind and rain directly below the aircraft), Tail Doppler radar (measuring wind speed and direction throughout the storm), Wide-Swath Radar Altimeter (wave height below the aircraft), and flight-level instruments are all shown. During … Continue reading Hurricane and Ocean Testbed Technical Workshop

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 how aircraft data are ingested into forecast models for tropical cyclones published in the Annals of the New York Academy of Science

This book chapter reviews how data are ingested into computer models and summarizes recent advances in how data relevant to tropical cyclones are used. Figure.  The impact of ingesting hurricane hunter data on predictions of storm intensity from NOAA’s state-of-the-art hurricane model, the Hurricane Weather Research and Forecast Model.  In this figure, the impact of … Continue reading Review of how aircraft data are ingested into forecast models for tropical cyclones published in the Annals of the New York Academy of Science

Study relating the structure of the area in a tropical cyclone closest to the surface and intensity released online in Monthly Weather Review

The study analyzes Doppler radar profile analyses to advance our understanding of how and why tropical cyclones intensify or weaken in relation to the shape of the vortex (whether the wind field is narrow or broad) and boundary-layer structure.  Example of a mean composite of only the radial wind velocity from airborne Doppler wind profile … Continue reading Study relating the structure of the area in a tropical cyclone closest to the surface and intensity released online in Monthly Weather Review

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 completes historic missions into Hurricanes Earl, Fiona, and Ian

Despite the late start to the 2022 Atlantic Hurricane season, NOAA Hurricane Hunters have been very busy flying operational and research missions into and around Hurricanes Earl, Fiona, and Ian during the last few weeks.

NOAA Researchers fly a series of missions into Hurricane Ian

Outer rainband of Hurricane Ian as seen from NOAA 43 "Miss Piggy" Scientists from NOAA's Hurricane Research Division and NOAA's National Environmental Satellite Data and Information Service have flown a series of missions into Hurricane Ian from the time it was a tropical depression in the eastern Caribbean. On board both NOAA P3s (Kermit & … Continue reading NOAA Researchers fly a series of missions into Hurricane Ian

Thirtieth anniversary of Hurricane Andrew’s landfall in South Florida

Hurricane Andrew made landfall on August 24, 1992, near Homestead, Florida, becoming one of the most catastrophic hurricanes in U.S. history. It had an extremely low central pressure of 922 millibars and maximum sustained wind speeds estimated at 165 miles per hour. The storm rapidly intensified less than 36 hours before landfall, leaving most residents less … Continue reading Thirtieth anniversary of Hurricane Andrew’s landfall in South Florida
