Colleagues, family, and friends mourn the passing on Sept. 28, 2020, of Dr. James “Doc” McFadden, a dedicated public servant who, over the course of his 57 year career, has immeasurably influenced the evolution of airborne data collection at NOAA. Dr. McFadden most recently served as chief of programs for the NOAA Aircraft Operations Center (AOC), where […]
Every weekday AOML scientists and collaborators get together for 30 minutes to discuss the tropical forecast and potential opportunities to conduct research. This week employees from the National Hurricane Center (NHC) led the forecast discussion. The decreased activity in the Atlantic basin was the primary topic of this week’s map discussions. NHC forecaster Dave Zelinsky […]
The NOAA Hurricane Hunters finished reconnaissance for Hurricane Teddy on September 22, taking off for their final flight at 5 AM EDT from Patuxent River, MA. Tasked by the National Hurricane Center (NHC), this mission focused on assessing the characteristics of Teddy’s circulation in anticipation of tropical cyclone impacts in Atlantic Canada. AOML hurricane scientists provided […]
September’s science meeting consisted of three presentations: Andy Hazelton – “HAFSV0.1B (HAFS-globalnest) performance for Hurricane Laura: Verification and Evaluation of TC structure” Evan Forde – “Identification of Atlantic Basin Tropical Cyclones in Proximity to Significant Dry Air Events in Total Precipitable Water Imagery (1987-2015)” Sim Aberson – “In Search of the Elusive Eyewall Me/iso-scale ?” The three […]
NOAA’s Hurricane Hunters will continue reconnaissance for Hurricane Teddy on September 22 after one P-3 aircraft relocates from St. Croix to Norfolk, VA on Monday, September 21. This mission is at the request of the National Hurricane Center (NHC) to track the strength and location of Teddy as forecasters expect it to impact the Canadian […]
A new study published in Remote Sensing uses radar data from NOAA’s P-3 Hurricane Hunter aircraft to determine the characteristics a satellite would need to measure the surface wind in a tropical cyclone between areas of heavy rainfall. This study finds that satellites with higher resolution can measure larger regions of heavy rainfall. Using satellites to increase observations of […]
NOAA’s Hurricane Hunters continue reconnaissance for major Hurricane Teddy, conducting numerous science experiments developed by AOML and its collaborators. The two P-3 aircraft will take off from St. Croix, U.S. Virgin Islands at 10 AM and 6 PM EDT, respectively, on September 18 as tasked by AOML’s Hurricane Research Division. AOML hurricane scientists will guide and […]
AOML’s Hurricane Research Division tasked the NOAA Hurricane Hunters to explore the atmospheric conditions associated with Teddy’s development. AOML scientists providing support for P-3 and G-IV flights into Teddy plan to manage multiple objectives laid out in their Intensity Forecasting Experiment (IFEX). G-IV reconnaissance will continue on September 18 for Hurricane Teddy, collecting crucial dropsonde measurements in the […]
AOML’s Hurricane Research Division tasked all three NOAA Hurricane Hunter aircraft to perform science operations into Hurricane Teddy, now a category-2 tropical cyclone and still intensifying in the mid-Atlantic. Operations into Teddy began yesterday with G-IV aircraft objectives defined in AOML’s Synoptic Flow Experiment as part of NOAA’s Hurricane Field Program. The G-IV took off for […]
Summary: The Global Hawk, a drone or uncrewed aircraft system, has been used since 2010 to gather data to improve weather 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 […]
