This two-year, $190,000 Project Grant from the National Science Foundation's Geosciences program (CFDA 47.050) will support research investigating the relationship between the Madden-Julian Oscillation and Quasi-Biennial Oscillation. The principal investigator will develop an idealized theoretical model and conduct simulations using the System for Atmospheric Modeling to explore how the MJO may be damped by upward wave propagation into the stratosphere or influenced by cirrus clouds whose...
This two-year Project Grant from the National Science Foundation Division of Atmospheric and Geospace Sciences provides $190,000 to establish causality in the angular momentum budget of the atmosphere through insights from the quasi-biennial oscillation. The grant funds basic research activities under the Geosciences program (CFDA 47.050), which aims to strengthen understanding of the integrated Earth system. Research supported by this award will generate new knowledge about atmospheric dynamics...
This National Science Foundation project grant of $320,847 will fund research into the tropospheric response to stratospheric polar vortex disruptions and their application to subseasonal to seasonal weather prediction under the Geosciences program (CFDA 47.050). Principal investigators from the Massachusetts Institute of Technology will analyze observational datasets, climate model simulations, and ensemble forecasts to better understand how differences in the pattern of distortions during...
This $345,667 National Science Foundation project grant supports research to improve understanding of the effects of stratospheric polar vortex disruptions on tropospheric circulation and surface weather patterns. Funded under the Geosciences program (CFDA 47.050), which aims to expand knowledge of the integrated Earth system through atmospheric and ocean sciences research, the award will be completed by July 2025. The grantee, Atmospheric & Environmental Research Inc., will conduct data...
The University of Oklahoma was awarded a $308,680 project grant from the National Science Foundation's Geosciences program (CFDA 47.050) to conduct collaborative research on the coupling mechanism of the Madden-Julian Oscillation and Quasi-Biennial Oscillation through cloud-radiative feedback. Under this three-year award beginning July 1, 2023, the University will analyze satellite and reanalysis dataset observations, conduct climate model simulations, and use a linear model to explore the...
This Project Grant award of $104,871 from the National Science Foundation's Geosciences Program (CFDA 47.050) supports collaborative research by Northern Illinois University to improve understanding of quasi-linear convective systems (QLCS), a significant weather hazard that can produce tornadoes and extreme winds. The research team will create a climatology of QLCS events over the past 10+ years using advanced weather radar data, which will be combined with idealized numerical modeling to study...
This is a National Science Foundation (NSF) Project Grant award under the Geosciences program (CFDA 47.050) totaling $1,010,185 with a period of performance from September 1, 2024 to August 31, 2029. The award was made to Cornell University to conduct research that applies extreme event attribution methodologies to quantify the influence of stratospheric variability, such as sudden stratospheric warmings, on the likelihood and severity of subseasonal extreme weather events like cold air...
This Project Grant award in the amount of $424,952 from the National Science Foundation's Geosciences Program (CFDA 47.050) will support collaborative research to study the connections between tropical heating, planetary-scale stationary waves, and extratropical storm track activity. The study, to be conducted by two Ph.D. students at Stony Brook University, aims to demonstrate how tropical deep convection and variations in zonal mean temperature gradients influence the behavior of extratropical...
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 $196,453 National Science Foundation project grant supports research into the downward progression of temperature anomalies during sudden stratospheric warmings. Specifically, the University of Colorado Boulder will analyze characteristics of temperature anomalies and atmospheric waves using satellite and model data, conduct numerical simulations of wave propagation, and investigate potential pre-conditioning through changes in the zero-wind line height via ensemble simulations....
