HRD researchers discussed the results from the 4 G-IV and 4 P-3 missions into Central Pacific Hurricane Lane (19-23 August 2018) representing the first NOAA P-3 mission to fly a Central Pacific storm. The agenda for the discussion was: Agenda: Storm Overview (Jon Zawislak) Missions Overview (Jon Zawislak) Deployment Overview (Jon Zawislak) CPHC Feedback (Tom Birchard, […]

Summary: In this study, we looked at radar, thermodynamic (temperature and humidity), and sea surface temperature data from the National Oceanic and Atmospheric Administration Hurricane Hunter and National Aeronautics and Space Administration aircraft in Hurricane Earl (2010). We found that there are different types of downdrafts (air moving downward) near the strongest part of the […]
During the final NOAA flight into Hurricane Lane, history was made when (l-r) Lisa Bucci, Kelly Ryan, Kathryn Sellwood, and Heather Holbach became the first all-female science crew on a hurricane hunter mission. Serendipitously, the mission was conducted into the hurricane when it was category 5, the strongest category of hurricane, with sustained winds of […]
Summary: The Global Hawk, a drone or uncrewed aircraft system (UAS), has been used since 2010 to gather data to improve forecasts. The Global Hawk can release dropsondes that measure temperature, pressure, humidity, and wind up to four times every second, starting at an altitude of up to 60,000 feet until it falls to the […]
NOAA42: The final P-3 mission into Hurricane Lane in the Central Pacific landed around 11:30 PM HST last night. The airplane is returning to the mainland today. NOAA49: The final G-IV synoptic surveillance mission took off from Honolulu at 7:30 AM HST this morning, and will be returning to the mainland tomorrow. No further missions […]
Tuesday, August 21, 2018: NOAA42: The EMC-tasked operational mission into Hurricane Lane in the Central Pacific, that was scheduled to takeoff from Honolulu, Hawai’i at 4 AM HST (10 AM EDT), was cancelled. There will, however, be another EMC-tasked mission today, scheduled for takeoff at 4 PM HST (10 PM EDT). The flight track for this mission […]
On August 21, 1873, the U.S. Army Signal Corps’ National Weather Service issued a hurricane warning extending from Cape May, NJ to New London, CT. This was the first such warning issued by the Service, which was formed just three years prior. The hurricane was a classic Cape Verde storm, forming near the islands on […]
The purpose of the observation team meetings is to bring together the people who use observations in their research on a regular basis to discuss issues they’re having, provide updates on observations they’re analyzing or collecting, and any other information that may be of interest to the broader group. These meetings are also an excellent […]
