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 Project Grant from the National Science Foundation Division of Atmospheric and Geospace Sciences, under the Geosciences program (CFDA 47.050), provides $144,071 to Northwest Research Associates, Inc. to conduct collaborative research understanding interactions between mesoscale and microscale flows in the stable boundary layer over shallow terrain. The research will analyze data collected through the NSF-funded SAVANT campaign to deduce empirical relationships defining flow patterns that...
- This National Science Foundation (NSF) Project Grant award under the Geosciences program (CFDA 47.050) provides $380,375.00 to the University of Texas at Dallas (UTD) to study turbulence and sea spray aerosol transport in the marine atmospheric boundary layer of coastal regions. The 3-year project will make field observations using a scanning Doppler lidar and existing meteorological/oceanographic data to quantify limitations in current modeling techniques and identify interactions between waves...
- This Project Grant from the National Science Foundation Division of Atmospheric and Geospace Sciences, under the Geosciences federal grant program (CFDA 47.050), provides $273,725 to the University of South Carolina from August 15, 2022 to July 31, 2025. The funding will support research to improve understanding of interactions between mesoscale and microscale flows in the stable boundary layer over shallow terrain under nighttime conditions. Researchers will analyze data collected through the...
- 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 $280,247 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) will fund collaborative research by the Massachusetts Institute of Technology (MIT) to develop advanced, AI-powered modeling capabilities for small-scale turbulence within the coupled air-sea boundary layers. The research aims to improve understanding of how surface waves and resulting turbulent processes regulate the exchange of mass, momentum, and energy between the atmosphere and...
- This $298,225 federal Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports a collaborative research project at Southern Methodist University (SMU) to develop advanced AI-powered modeling capabilities for examining small-scale turbulence within the coupled air-sea boundary layers. The research aims to improve understanding of how surface waves and their resulting turbulent processes regulate the exchanges of mass, momentum, and energy between the...
This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $202,000 to investigate how atmospheric boundary layer turbulence and scalar transport are impacted by complex, vegetated topography under unstable daytime conditions. The core of the project involves extending the researcher's prior large eddy simulation database to include the effects of heat and moisture in unstable convective conditions. This will address two key science questions: 1) how do atmospheric boundary layer flow physics above forested periodic hills change with the introduction of unstable stratification, and 2) whether the new idealized topography framework can be used to classify important turbulent and scalar transport terms across different terrain types under unstable stratification. Additionally, the researcher will conduct a simulation of the area surrounding the Amazon Tall Tower Observatory to compare model results with observational data. The expected outcome of this 2-year project is to improve weather models and forecasting capabilities, particularly in critical areas like agriculture and wildfires.
