The book discusses how to make weather warnings most effective through communication and partnerships. Warnings are the result of a process from weather observations to weather forecasts to hazard forecasts to socio-economic impact forecasts to warning messages to decisions on how to avoid or mitigate the hazard. The book offers a framework across government, private […]
Bill Ramstrom is a Senior Software Engineer at the Cooperative Institute for Marine and Atmospheric Studies (CIMAS), which partners with the NOAA Atlantic Meteorological and Oceanographic Laboratory (AOML) in Miami, FL. Bill created and coded the first ever moving “nest” for the Unified Forecast System (UFS), a modeling system that supports NOAA’s Weather and Climate […]
Learn about the new William M. Lapenta Laboratory for the Hurricane and Ocean Testbed, the new Hurricane Analysis and Forecast System, the impact of Uncrewed Aerial Systems on hurricane forecasts, and more… The newsletter is available here.
This study uses a state-of-the-art hurricane modeling system developed at the NOAA/Atlantic Oceanographic and Meteorological Laboratory’s Hurricane Research Division, the Basin-Scale Hurricane Weather Research and Forecast (HWRF-B) model, to demonstrate a link between an oceanographic process called coastal downwelling and the intensification of tropical cyclones (TCs or hurricanes) near landfall. We show that coastal downwelling […]
This study examines the impact of assimilating Doppler Wind Lidar (DWL) data on hurricane prediction in the operational Hurricane Weather Research and Forecasting system. A series of experiments were conducted to identify the best way to assimilate the DWL data in comparison to assimilation of Tail Doppler radar data. A new data thinning method was […]
The primary goal of NOAA/OAR/AOML’s Hurricane Research Division (HRD) is to improve the understanding and prediction of tropical cyclones (TCs). While this improvement can be accomplished from a variety of approaches, a unique capability of HRD is the routine collection and analysis of airborne observations within the tropical cyclone inner core and its atmospheric and […]
Forecast models that follow individual tropical cyclones (TCs), like NOAA’s Hurricane Weather Research and Forecasting (HWRF) model, have contributed to significant improvement of intensity forecasts for over a decade. The original HWRF could only follow one TC, but recent advances allow individual multiple nests to follow more than one TC. This is the first time that the […]
The study introduces a new database that is freely available and consists of over 900 airborne Doppler radar analyses collected between 1997–2020. We demonstrate the capabilities of the database by identifying how the structure of hurricanes changes depending on the strength of the storm, which provides a foundation for future research avenues and computer model […]
