Observations of Gravity Waves Radiating from Hurricanes Obtained from Research Aircraft and Surface Stations

This study extends the work presented by Nolan and Zhang (2017) who documented in-situ observations of gravity waves radiating from hurricanes. Data collected by NOAA P3 aircraft from recent hurricanes (Matthew in 2016, Harvey, Irma, and Maria in 2017) will be analyzed and compared to those from hurricanes in 2003 and 2004 reported by Nolan and Zhang (2017). In addition, surface pressure data measured during the passages of Hurricanes Matthew and Irma by four weather stations in the Miami area will be analyzed. These stations are part of the WeatherStem network which were modified to save data every one minute. We attempt to determine relationships between wave amplitudes, wave direction, and hurricane intensity and position.
