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 released online in Monthly Weather Review

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 … Continue reading HRD observation team monthly meeting – 18 October 2018

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 … Continue reading Paper on combining satellite data and data from the Global Hawk aircraft to improve forecasts published in Weather and Forecasting

Summary: A drone, what we call an unmanned aircraft system, can collect data in tropical cyclones (TCs) to improve forecasts. Scientists have used the Global Hawk drone that can fly at an altitude of up to 60,000 feet for over 24 hours at a time since 2010. The Global Hawk releases dropwindsondes that measure wind, … Continue reading Paper on the impact of dropwindsondes from the Global Hawk on forecasts published in Monthly Weather Review
