- The National Science Foundation (NSF) Division of Atmospheric and Geospace Sciences awarded a $126,139 Project Grant to the University of Virginia to advance research on measuring atmospheric turbulence and wind behavior using commercial off-the-shelf multi-rotor drone technology. The 12-month project, which runs from July 15, 2023 to June 30, 2024, aims to investigate the accuracy of drone-based turbulence measurements and how accuracy varies with drone size and weight. The work will be...
- This National Science Foundation (NSF) Geosciences program Project Grant award, with a total funding of $438,734, supports a collaborative research effort to study the turbulence in the stratified layer at the air-water interface caused by waves and wind. The research will be conducted through a combination of controlled laboratory experiments and state-of-the-art numerical simulations, with the goal of improving the representation of the ocean surface boundary layer in Earth-system models....
- The National Science Foundation (NSF) Division of Atmospheric and Geospace Sciences awarded a $440,764 Project Grant to Washington State University to study the influences of large turbulent eddies on the validity of the constant flux layer assumption in the unstable atmospheric surface layer. The 3-year project will leverage a field experiment over a large water body in Mississippi to collect a unique dataset that minimizes the influence of advective terms, enabling a more precise examination...
- This National Science Foundation (NSF) Geosciences Program (CFDA 47.050) Project Grant award in the amount of $353,715 will fund a collaborative research project to study the turbulence in the stratified layer at the air-water interface, as driven by waves and wind. The project will utilize a combination of controlled laboratory experiments and advanced numerical simulations (large-eddy simulations) to test the hypothesis that coupling between waves and wind-driven currents is necessary to...
- This $339,994 Project Grant awarded by the National Science Foundation's (NSF) Mathematical and Physical Sciences program supports research to advance the fundamental theoretical understanding of wave turbulence in the atmosphere and oceans. The award to New York University (NYU) will fund a multi-pronged effort combining theory and numerical modeling in three key areas: 1) investigating how broadband wave spectra can emerge from monochromatic wave sources through interactions with mean...
- The National Science Foundation (NSF) Geosciences program has awarded a $236,421 EAGER grant to the University of Utah to develop new approaches for representing land-atmosphere interactions in numerical weather prediction and climate models. The goal is to generalize the Monin-Obukhov Similarity Theory (MOST) to better account for turbulence anisotropy and facilitate its application across diverse surface configurations, such as mountainous terrain and forests. This research aims to improve the...
- This National Science Foundation (NSF) Geosciences Program (CFDA 47.050) Project Grant award for $1,195,922 will support the University of Washington's research project, "Exploration of Anisotropy and Inhomogeneity of Ocean Boundary Layer Turbulence." The project aims to provide the first direct observational study of the anisotropy and inhomogeneity of ocean surface boundary layer turbulence using custom-built acoustic instruments that drift with the water flow. The observations...
The National Science Foundation Division of Atmospheric and Geospace Sciences awarded a $458,858 Project Grant to The Regents of the University of Colorado to support research titled "COLLABORATIVE RESEARCH: NEW PATHWAYS TO ENHANCED TURBULENCE AND MIXING VIA KELVIN-HELMHOLTZ INSTABILITY TUBE AND KNOT DYNAMICS." The three-year award beginning November 1, 2021 will fund basic research into atmospheric dynamics and turbulence under the NSF's Geosciences program (CFDA 47.050). Specifically, the University of Colorado will investigate instability mechanisms that can enhance turbulence and mixing in the lower atmosphere. Through collaborative research, the project aims to advance understanding of Kelvin-Helmholtz processes and the development of tube-like vortex structures, with implications for atmospheric transport and dispersion. Insights gained will strengthen the national scientific enterprise by expanding fundamental knowledge of integrated Earth system processes, consistent with the goals of the NSF Geosciences program.
