Paper on how tropical cyclones in shear intensify published in Geophysical Research Letters
Summary: Tropical cyclones (TCs) are made up of thunderstorms (what we call convection), and these storms have strong winds moving up and down (what we call up- and downdrafts). Dry air enhances evaporative cooling (the same process that cools people when they sweat) from convective downdrafts, reducing the temperature and humidity in low levels; this […]

Paper on how downdrafts in hurricanes affect intensity published in Monthly Weather Review
Summary: This study looks at differences between tropical cyclones that strengthen and those that do not using data collected by dropsondes, small instruments released from hurricane hunter aircraft that measure wind, temperature, and moisture as they fall to the surface. Important Conclusions: 1. The fuel that supports tropical cyclones is the heat and moisture from […]
Paper on getting the best TC forecasts using NOAA’s G-IV published in Monthly Weather Review
Summary: During each hurricane season, NOAA’s Gulfstream-IV (G-IV) Hurricane Hunter aircraft measures wind, temperature, humidity, and pressure in and around hurricanes threatening the United States. An instrument called the dropwindsonde is released from the G-IV to collect the data as it falls to the ocean surface. The plane currently flies where we expect observations from the […]
Hurricane Field Program Update — Sunday, September 29, 2019, 10pm EDT
All three NOAA aircraft flew in and around Hurricane Lorenzo today, with both P3s flying the same tracks (at 8 and 10 kft) through the storm within 15 minutes of each other. The G-IV departed the storm just as the P3s were entering. The G-IV flew an HRD research mission in support of the NESDIS […]
