The NOAA Hurricane Hunter P-3 aircraft (NOAA42) is flying Tropical Depression 3 off the coast of North Carolina — the first NOAA missions of the 2018 hurricane season. The airplane took off from Lakeland at 4:30 AM EDT for an 8 hour mission. A second mission is planned for 4:30 PM. Below is the planned flight […]
OPERATIONS Saturday, July 7, 2018: No flights scheduled. Sunday, July 8, 2018: NOAA42: The P-3 is tasked by the Environmental Modeling Center (EMC) to fly a Tail Doppler Radar (TDR) mission into TD 3. Takeoff is scheduled for 4:30 AM ET (0830 UTC) from Lakeland Linder Regional Airport. Three HRD scientists will be on this […]

Dr. Kren presented a seminar titled “Observing System Simulation Experiments (OSSEs) and Observing System Experiments (OSEs) to evaluate the impact of current and future observing systems in the NCEP GDAS”. ABSTRACT: Observing System Experiments (OSEs) test the impact of current observing system platforms on analyses and forecasts, while Observing System Simulation Experiments (OSSEs) can evaluate […]

Summary: The CYclone Global Navigation Satellite System (CYGNSS) was launched into space on December 15, 2016, to improve hurricane (tropical cyclone) forecasts by measuring wind speed on the ocean surface. Since the tropical cyclones mostly occur over oceans where other wind data are usually not available, the new observations can measure their wind speeds. This […]
Prof. Bourassa presented a seminar titled “Ocean Applications of Satellite Measurements of Winds and Currents Through Ka-Band Scatterometry”. ABSTRACT: Ka-band scatterometry is of great use for a wide range of applications, and can be used to measure ocean surface winds and surface currents at relatively high resolution compared to traditional scatterometry. The sensitivity to wind direction […]
Since 1956, the Hurricane Research Division has carried out an annual field program in which data on Atlantic hurricanes is collected from a variety of platforms, primarily NOAA aircraft. Since the early 1970s plans for particular experiments were documented prior to the start of the season, to better allocate resources and personnel. This year’s plan […]
June’s science meeting consisted of three presentations: Sim Aberson – Extreme horizontal and vertical motions measured by dropsondes in tropical cyclones: 2017 update Erin Jones – Quantifying Spiral Gravity Waves Radiating from Tropical Cyclones Robert Rogers – Tropical Cyclone Vortex Development in Moderate Shear All the presentations are available on the anonymous ftp site at: ftp://ftp.aoml.noaa.gov/hrd/pub/blog/meetings/2018/Science/HRD_SciMeet_20180614.zip
