Cooperative Agreement NA15NES4400004

This three-year project grant from the National Science Foundation's Geosciences program (CFDA 47.050) provides $459,780 to the University of Miami Rosenstiel School of Marine and Atmospheric Science to advance understanding of tropical cyclone intensification dynamics in sheared environments. Specifically, the award supports research using the Hurricane Weather Research and Forecasting (HWRF) model and HWRF Ensemble Data Assimilation System (HEDAS) to analyze tropical cyclone energetics, vortex...

This Project Grant award from the National Science Foundation's (NSF) Geosciences Program (CFDA 47.050) to Embry-Riddle Aeronautical University, Inc. in the amount of $374,070 aims to better understand how different types of precipitation in tropical cyclones impact their maximum sustained wind speeds. The 4-year project will use airborne Doppler radar data and numerical weather prediction models to examine how precipitation modes, such as convection and stratiform rain, perturb the kinematic...

This $583,513 federal Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) will support research at the University of Washington to develop interpretable deep learning models that better predict the development of tropical cyclones, also known as hurricanes. The research aims to leverage the Madden-Julian Oscillation, a key atmospheric phenomenon, to improve forecasts of tropical cyclone genesis at 1-2 week lead times and explore extending predictions...

The National Science Foundation's Geosciences program awarded a $777,109 project grant to the University of Miami Rosenstiel School of Marine and Atmospheric Science (RSMAS) to study the structure, dynamics, and moisture budgets of tropical cyclones from the lower to upper troposphere. The project will leverage airborne Doppler radar observations, dropsonde measurements, satellite imagery, and high-resolution computer simulations to better understand the three-dimensional structure of the...

This $428,965 Cooperative Agreement awarded by the National Oceanic and Atmospheric Administration (NOAA) under the Weather and Air Quality Research program (CFDA 11.459) aims to develop and test a method for improving subseasonal-to-seasonal (S2S) precipitation outlooks for the contiguous United States. The project, led by Utah State University, will apply a new weather regime-Gaussian mixture model (WR-GMM) framework to NOAA's Climate Prediction Center's dynamical forecast outputs to produce...

This $499,802 federal Project Grant award, funded by the National Science Foundation's Geosciences program (CFDA 47.050), aims to improve coastal community resilience to hurricane wind-related hazards and potential compounding hazards. The project will leverage Doppler radar wind retrievals and near-surface wind measurements to better understand the low-level wind profiles of landfalling hurricanes. Researchers will use advanced simulation techniques and artificial intelligence to predict...

This Project Grant from the National Science Foundation's Division of Atmospheric and Geospace Sciences, under the Geosciences program (CFDA 47.050), provides $701,663 to Florida State University to conduct collaborative research on the intensity and size relationship of tropical cyclones. The research aims to better understand this relationship through exploring how the inward radial loss rate of absolute angular momentum and effective absolute angular momentum values depend on environmental...

This three-year, $533,747 project grant from the National Science Foundation Division of Atmospheric and Geospace Sciences will fund research into how the intensity and impacts of tropical cyclones may change in response to climate warming after landfall. Specifically, the grantee will conduct idealized and real-data case studies in pseudo-global warming scenarios to assess potential shifts in tropical cyclone activity and landfall location, changes in precipitation patterns and the extent of...

This three-year, $405,234 Project Grant from the National Oceanic and Atmospheric Administration will fund research at the University of Colorado Boulder to develop initialization strategies for the Unified Forecast System coupled atmosphere-ocean numerical forecast model. The goal is to improve probabilistic skill scores for subseasonal-to-seasonal forecasts of 2-8 weeks by ensuring initial ensemble perturbations project onto oscillating eigenfunctions of the Koopman and Perron-Frobenius...

This Project Grant award from the National Science Foundation's Geosciences program (CFDA 47.050) will fund a $425,403 study by George Mason University to characterize the effects of hurricanes on the upper atmosphere. The research team will use satellite observations and climate models to analyze how hurricanes impact winds, temperatures, and atmospheric waves in the thermosphere and ionosphere, tens of kilometers above the Earth's surface. This work aims to provide new insights into the...
