Summary: The Global Hawk, a drone or unmanned 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 …
During a test flight on 31 July, the NOAA Aircraft Operations Center (AOC) released a dropwindsonde and transmitted the wind, pressure, temperature, and humidity data to the ground and around the world via the Global Telecommunications System. Since the advent of dropsondes in the 1940s, only data from a few of the many observations could …
Summary: The warm ocean provides the energy for tropical cyclones to form and intensify. Knowing what is happening in the air immediately above this warm ocean (called the boundary layer) tells us how that energy gets into the air. So, it is important to know what is happening there to accurately predict how strong a …

Summary: Because satellites are observing the weather all the time, there are almost always satellite data available around hurricanes or tropical cyclones (TCs). On the other hand, Hurricane Hunter aircraft can only reach TCs when the storms are near land and when airplanes and crews are available. When Hurricane Hunter missions are planned, the regular …
HRD researchers discussed the results from the 4 P-3 missions into AL03 Tropical Storm Chris (8-9 July 2018). The agenda for the discussion was: Missions Overview (Jon Zawislak) Mission Summaries 20180708H1 TDR (Kelly Ryan) 20180708H2 TDR (Hui Christophersen) 20180709H1 TDR (Kelly Ryan) 20180709H2 TDR (Gus Alaka) Discussion Slides from the debrief are available at: ftp://ftp.aoml.noaa.gov/pub/hrd/blog/meetings/2018/HFP/2018HFP_Chris_Debrief.pptx
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 …

July’s science meeting consisted of four presentations: Erin Jones – Simulating Observations of Gravity Waves Radiating from Hurricanes Miguel Cortez - Summer 2018 Nerto Work Plan Sim Aberson – A comparison of track forecasts from NOAA’s GFS and ECMWF’s IFS for Hurricane Irma Jon Zawislak - 2018 NOAA/AOML/HRD Hurricane Field Program Intensity Forecast Experiment (IFEX) …
Intensity Forecast Experiment (IFEX) Program Director Jon Zawislak and HRD Director Frank Marks briefed the Aircraft Operations Center (AOC) personnel at their brand new facility at Lakeland Linder Regional Airport on IFEX plans for 2018 and Hurricane Forecast Improvement Project progress, respectively. The two presentations are available in a .zip archive on the anonymous ftp …
