This Project Grant award of $464,291 from the National Science Foundation's Geosciences Program (CFDA 47.050) supports research to understand the sources of spatial variability in low-level stratocumulus clouds and how this variability influences cloud and precipitation processes. The primary objectives are to identify microphysical drivers of spatial variability, such as condensation, stochastic collisions, turbulence-enhanced collision kernels, and giant aerosol particles, and assess their...
This $941,193 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports research to further develop a theory on the invariance of cloud size distribution under varying climate conditions. The research aims to evaluate whether certain cloud properties, such as the relationship between cloud size and number, remain consistent despite changes in atmospheric climate and chemical composition. The work seeks to understand the underlying physical mechanisms...
This three-year, $511,918 project grant from the National Science Foundation's Geosciences program (CFDA 47.050) funds research to develop a new framework for advancing climate model representations of cloud and convective processes. The grantee, Columbia University, will conduct fully-coupled, isotope-enabled climate simulations for the Last Glacial Maximum, Mid-Holocene, and Pre-Industrial periods using an ensemble of cloud and convective parameter sets. Paleoclimate data assimilation will...
This $425,395 National Science Foundation project grant supports research into understanding low-cloud feedbacks using large-eddy simulation of spatially developing cloud transitions from February 15, 2022 through January 31, 2027. Funded through the Geosciences program (CFDA 47.050), the research aims to address limitations in modeling low-cloud behavior over large areas by developing a hierarchy of large-eddy simulation model configurations at different scales. Several experiments are...
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 $112,582 National Science Foundation project grant supports foundational research to improve understanding and forecasting of downdrafts in deep convection through June 2025. Funded under the Geosciences program (CFDA 47.050), the research will analyze the influence of atmospheric properties on downdraft forces and origins using theoretical and idealized modeling. Insights will enhance downdraft representation in weather and climate models to improve prediction of thunderstorm impacts,...
The Trustees of Columbia University in the City of New York Sponsored Projects Administration Division (Columbia University) was awarded a $117,062 project grant from the National Science Foundation's Geosciences program (CFDA 47.050) to conduct research on the coupling mechanism of the Madden-Julian Oscillation and Quasi-Biennial Oscillation through cloud-radiative feedback. The award period is from July 1, 2023 to June 30, 2026. As part of the grant, Columbia University researchers will...
This National Science Foundation project grant of $399,905 provides funding from August 1, 2022 to July 31, 2025 under the Geosciences program (CFDA 47.050) to develop a new poloidal convection model and multi-scale description of moist circulations in tall cumulus clouds. The University of California, Davis will test and further develop the poloidal model framework to incorporate both ascending and descending air motions within convective clouds. This will allow for new understanding of cloud...
This $596,100 Project Grant awarded by the National Science Foundation's Geosciences Program (CFDA 47.050) supports research by the University of California San Diego's Scripps Institution of Oceanography to develop a climate model that can simulate the interactions between small-scale cloud dynamics and large-scale climate processes. The research aims to better understand the net effect of clouds on climate, accounting for the two-way interactions between clouds and climate that determine their...
This $1,389,411 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports the continuing research efforts of the Principal Investigator to understand the probability distribution of rainfall intensity and its relationship to climate change. The key objectives include: Explaining why increases in precipitation intensity in a warming climate exceed expectations based solely on increased water vapor content. Exploring how the suppression of convection due...

This Project Grant award of $377,905 from the National Science Foundation's Geosciences Program (CFDA 47.050) supports research to understand the drivers of cloud and precipitation variability in low-level stratocumulus clouds. The research team at Columbia University will run large-eddy simulations using a Lagrangian particle-based microphysics model to identify the sources of microphysical variability, such as condensation, stochastic collisions, and giant aerosol particles, and how this variability impacts cloud and precipitation processes. The results will be used to train a Bayesian observationally-constrained statistical-physical scheme with a stochastic component. The research aims to improve modeling of clouds and their effects on Earth's radiation balance, while also enhancing the training of the next generation of atmospheric scientists. The award period is from June 15, 2025 to May 31, 2028.
