AOML Scientists use Hurricane Hunter Data to Analyze Gaps in Hurricane Rain Coverage

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 … Continue reading AOML Scientists use Hurricane Hunter Data to Analyze Gaps in Hurricane Rain Coverage

Major Hurricane Teddy missions provide unique dataset for AOML hurricane scientists

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 … Continue reading Major Hurricane Teddy missions provide unique dataset for AOML hurricane scientists

NOAA Hurricane Hunters conduct missions investigating Hurricane Teddy

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).  Flight track planned for the NOAA P-3 mission into Hurricane Teddy. G-IV reconnaissance will continue on … Continue reading NOAA Hurricane Hunters conduct missions investigating Hurricane Teddy

AOML shifts its reconnaissance and research efforts to Hurricane Teddy, reviews Hurricane Sally data

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 … Continue reading AOML shifts its reconnaissance and research efforts to Hurricane Teddy, reviews Hurricane Sally data

Paper on the optimal way to gather observations to improve winter-storm forecasts published in Meteorological Applications

Summary: The Global Hawk, a drone or unmanned 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 … Continue reading Paper on the optimal way to gather observations to improve winter-storm forecasts published in Meteorological Applications

Hurricane Hunter flights continue into Sally and Teddy

NOAA's P-3 aircraft wrapped up their sequence of missions into Hurricane Sally prior to the system's eventual landfall along the central Gulf Coast. Tasked by the National Hurricane Center (NHC), its final flight took off on September 15 at 9:30 EDT from Lakeland, FL.  Hurricane scientists supporting P-3 missions into Hurricane Sally identified the location … Continue reading Hurricane Hunter flights continue into Sally and Teddy

Sally intensifies near the Gulf Coast as observed by NOAA reconnaissance

NOAA's G-IV and two P-3 Hurricane Hunter aircraft took off from Lakeland, FL, at 1:30 PM, 10:30 AM, and 4:30 PM EDT, respectively, on September 14th for continued missions investigating Hurricane Sally's circulation. Tasked by the Environmental Modeling Center (EMC), NOAA's P-3 aircraft each performed 4 passes through the system's center, observing the atmospheric conditions in all … Continue reading Sally intensifies near the Gulf Coast as observed by NOAA reconnaissance
