Paper on getting the best TC forecasts using NOAA’s G-IV released online 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 … Continue reading Paper on getting the best TC forecasts using NOAA’s G-IV released online in Monthly Weather Review
Paper on the tropical cyclone diurnal cycle as seen in a forecast model published in Monthly Weather Review
Summary: As tropical cyclones (TCs) move across the oceans, they begin to expand each day around sunset, with clouds reaching hundreds of miles from the center by the following afternoon. This daily “exhale” of the clouds is a feature of what we call the TC diurnal cycle. This study looks at the this cycle in … Continue reading Paper on the tropical cyclone diurnal cycle as seen in a forecast model published in Monthly Weather Review
Paper on possible improvements to forecasts from additional radio-occultation satellite data published in Monthly Weather Review
Summary: The Constellation Observing System for Meteorology, Ionosphere, and Climate (COSMIC) are a set of satellites that were launched in 2006 and orbit the earth about 500 miles above ground. They use radio signals from Global Positioning System (GPS) satellites in a process called “radio occultation” to measure temperature and moisture with high accuracy every 100 … Continue reading Paper on possible improvements to forecasts from additional radio-occultation satellite data published in Monthly Weather Review

Paper on the impact of new satellite wind velocity data on hurricane forecasts published in Monthly Weather Review
Summary: The CYclone Global Navigation Satellite System (CYGNSS) was launched into space on December 15, 2016, to improve hurricane (tropical cyclone) forecasts by measuring wind speed on the ocean surface. Since the tropical cyclones mostly occur over oceans where other wind data are usually not available, the new observations can measure their wind speeds. This … Continue reading Paper on the impact of new satellite wind velocity data on hurricane forecasts published in Monthly Weather Review
