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

HRD scientists attend Hurricane Forecast Improvement Program Annual Meeting

Last week, researchers from HRD attended the 2022 Hurricane Forecast Improvement Program (HFIP) Annual Meeting in Miami, Florida.  Group photo of some of the participants of the 2022 HFIP Annual Meeting, both in person and virtually.  The primary objective of this meeting was to discuss key HFIP strategies including advances to NOAA's next-generation Hurricane Analysis and Forecast … Continue reading HRD scientists attend Hurricane Forecast Improvement Program Annual Meeting

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

Study on how weak, disorganized tropical cyclones become upright allowing for intensification published in the Journal of Geophysical Research

This study shows how weak, disorganized tropical cyclones that have different center locations with height (misalignment) can develop a vertically aligned structure. The ability to predict whether and when a tropical cyclone will become aligned is important for intensity change forecasts, as storms can intensify quickly after achieving it. This study will help improve forecasts … Continue reading Study on how weak, disorganized tropical cyclones become upright allowing for intensification published in the Journal of Geophysical Research

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

Study of what controlled the track of Hurricane Dorian in 2019 released online in Monthly Weather Review

This study looked at a collection (ensemble) of 80 runs of a hurricane model for Hurricane Dorian to learn why some got the forecast right and others got it wrong.  The study shows how useful ensembles can be for understanding how hurricanes move, and also shows that it is critical to forecast what is happening … Continue reading Study of what controlled the track of Hurricane Dorian in 2019 released online in Monthly Weather Review
