Study on using hard-to-obtain observations from uncrewed aircraft in Hurricane Maria to improve analyses and forecasts published in Monthly Weather Review

For the first time, near-surface observations obtained by small Uncrewed Aircraft Systems (or drones) in a major hurricane (Hurricane Maria of 2017) were utilized in a state-of-the-art computer. Such observations are impossible to obtain using regular hurricane hunter aircraft. Furthermore, a new technique to identify and eliminate observations that may not be useful in improving analyses or … Continue reading Study on using hard-to-obtain observations from uncrewed aircraft in Hurricane Maria to improve analyses and forecasts published in Monthly Weather Review

Study on how the direction of wind shear impacts tropical cyclone intensity published in Monthly Weather Review

This is the first study to examine how the direction of the wind shear changes how much heat and moisture is available to the TC and how it influences TC intensity change.  These results provide TC forecasters another tool to predict intensity change. ■ Summary:  The amount of wind shear, the change of winds with … Continue reading Study on how the direction of wind shear impacts tropical cyclone intensity published in Monthly Weather Review

Study on how to improve model forecasts of the region closest to the ocean surface published in The Journal of the Atmospheric Sciences

Summary:  Turbulence is made up of random and continuously changing wind.  It is important in tropical cyclones (TCs) because turbulence in the lowest 1-2 km of the free atmosphere (the planetary boundary layer or PBL) affects TC intensity and structural change. Meteorologists use computer models to forecast the weather, including TCs. These models forecast the … Continue reading Study on how to improve model forecasts of the region closest to the ocean surface published in The Journal of the Atmospheric Sciences

HRD scientists participate in the 34th American Meteorological Society Conference on Hurricanes and Tropical Meteorology

34th Conference on Hurricanes and Tropical Meteorology Virtual Meeting The 34th AMS Conference on Hurricanes and Tropical Meteorology was held virtually 10-14 May after being postponed from 2020. This is the premiere meeting for operational and research scientists who work on understanding and forecasting tropical cyclones and other tropical weather around the world.
