This summer during the 2022 Atlantic hurricane season, scientists at NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML) will once again be on the frontlines helping NOAA prepare the public for severe weather. They will also conduct new research on the complex processes of how tropical cyclones form, develop, and dissipate. AOML’s operational missions tasked by NOAA’s Environmental […]
The Airborne Vertical Atmospheric Profiling System (AVAPS™) is held annually by the National Center for Atmospheric Research (NCAR) Earth Observing Laboratory to discuss Science, Operations and Dropwindsonde Technology, along with having an open discussions for the different topics. NCAR is sponsored by the National Science Foundation. HRD scientists made two presentations at the recent meeting […]
On Saturday, May 14th, AOML’s Hurricane Research Division participated in the 2022 Eye of the Storm outreach event at Ft. Lauderdale’s Museum of Discovery & Science. HRD scientists answered questions about flying into hurricanes and how the data get into the computer models to improve the forecast. National Weather Service/National Hurricane Center table talked about […]
We test how different groups of observations, which reach the computer that run weather models at different times, impact the model forecast. We find that by not using the observations that arrive late, the forecast is much worse, showing the importance of quick transmission of observations. Direct observations (those measured within the atmosphere) have a greater […]

Alex Mitchell presented a seminar titled “The Governing Dynamics and Predictability of Recurving EPAC Tropical Cyclones”. ABSTRACT: Infrequent recurving eastern North Pacific (EPAC) tropical cyclones (TCs) can threaten life and property along the West Coast of North America primarily through flooding associated with heavy rainfall. These recurving EPAC TCs are most likely to occur during […]
Prof. Bosart presented a seminar titled “Impact of Recurving WPAC and EPAC Tropical Cyclones on Extreme Weather and Wildfire Events over the Western CONUS in Late Summer 2020”. ABSTRACT: Persistent upper-level ridging over the Rockies and an unusually weak summer monsoon that failed to bring much needed rain to the parched Southwest further favored extensive […]
Forecasting turbulence is important in forecasting tropical cyclones (TCs). Turbulence is made up of random and continuously changing wind, in small areas 100 m or less across, but meteorologists forecast TCs using computer models on grids with each point several kilometers from each other. As turbulence is much smaller than these grids, it is typically […]
This paper explores the effect of mountainous terrain on the structure of a tropical cyclone eyewall by using a numerical model to simulate the landfall of a typhoon in the Central Mountain Range (CMR) of Taiwan and its reemergence over water after crossing the CMR. It was found that the presence of the CMR disrupted […]
