This National Science Foundation (NSF) Division of Atmospheric and Geospace Sciences Project Grant award to Colorado State University (CSU) is for $254,826 over 3 years, starting on July 1, 2023. The award is funded under the NSF Geosciences program (CFDA 47.050), which supports basic research to expand fundamental knowledge and understanding of the integrated Earth system. The project focuses on examining the relationship between the trade wind inversion layer and the seasonal development of...
The University of California San Diego received a $680,406 Project Grant award from the National Science Foundation Division of Atmospheric and Geospace Sciences on July 15, 2021 to undertake a process-oriented investigation of double Intertropical Convergence Zone (ITCZ) biases in the National Center for Atmospheric Research Community Earth System Model. The research will be performed by the Scripps Institution of Oceanography through June 30, 2024. The investigation seeks to improve...
This National Science Foundation Project Grant award of $172,774 provides funding from February 1, 2023 through January 31, 2024 to support collaborative research examining interhemispheric and zonal asymmetries of the Intertropical Convergence Zone (ITCZ). Funded under the Geosciences program (CFDA 47.050), the award will advance understanding of regional variations in ITCZ latitude and properties through a combination of observational analysis and customized Earth system model simulations....
This Project Grant award of $538,591 from the National Science Foundation's Geosciences Program (CFDA 47.050) supports research to understand the relationship between tropical sea surface temperatures and the temperature of the tropical tropopause layer (TTL), which acts as a gateway for water vapor and ozone entering the stratosphere. The research involves conducting idealized modeling experiments using different climate models to reconcile two competing theories for how tropical sea surface...
This Project Grant award of $711,800 from the National Science Foundation's Geosciences Program (CFDA 47.050) supports research by Colorado State University to investigate the impact of tropical Pacific Ocean rain layers on weather and climate patterns, such as the Madden-Julian Oscillation and El Niño events. The research explores how the formation of a cold lid, or stable layer, from fresh rainwater on the ocean surface can delay and then intensify convective cloud development, with...
The National Science Foundation (NSF) Division of Atmospheric and Geospace Sciences awarded a $297,316 project grant to the New Jersey Institute of Technology (NJIT) to conduct collaborative research on convective processes in the tropics. The project, which runs from January 1, 2024 to December 31, 2026, aims to improve understanding of the interaction between small-scale cloud and storm details and large-scale rainfall patterns in the tropics. Key activities include leveraging advanced...
This National Science Foundation (NSF) Division of Atmospheric and Geospace Sciences Project Grant award, with a total funding amount of $532,712, supports collaborative research to investigate the physical processes underlying transitions in marine stratocumulus cloud cover over the eastern North Atlantic region. The research aims to develop a causal framework to better understand the complex interactions that drive changes in cloud structure, from continuous stratocumulus layers to more broken...
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 of $655,738 supports research by the New Mexico Institute of Mining and Technology (New Mexico Tech) to develop a theory of tropical convective precipitation. The research aims to relate the characteristics of tropical convection over oceans to the large-scale atmospheric conditions. This work extends previous field campaign data analysis to incorporate data from weather reanalysis products,...
The National Science Foundation's Geosciences program has awarded a $332,982 Project Grant to the University of Illinois. The grant, awarded on November 15, 2023, will fund collaborative research to understand the links between tropical cyclones and tropical circulation under climate change. The research will leverage two idealized configurations of the Community Earth System Model to isolate the mechanisms by which changes in atmospheric overturning cells, such as the Hadley and Walker Cells,...
