- The National Science Foundation Division of Atmospheric and Geospace Sciences awarded $835,425 to the Scripps Institution of Oceanography at the University of California San Diego on July 1, 2026, under the Geosciences program (CFDA 47.050) to investigate how the Atlantic Meridional Overturning Circulation (AMOC) influences near-term changes in surface atmospheric conditions globally. The project addresses two core research questions: the mechanisms by which AMOC decline impacts radiative...
- This $1,482,996 National Science Foundation project grant supports research at the University of California, Los Angeles to diagnose and understand the mechanisms behind warm season extreme weather over central and intermountain United States. The grant is funded through the NSF's Geosciences program (CFDA 47.050), which aims to strengthen understanding of the integrated Earth system through atmospheric, earth, and ocean sciences support. Specifically, the UCLA researchers will apply statistical...
- This $784,389 National Science Foundation project grant under the Geosciences program (CFDA 47.050) supports research into the causes of sea surface temperature fluctuations in the North Atlantic Ocean and their climatic impacts. The University of California, Riverside will conduct climate model simulations using the Community Earth System Model to explore the roles of natural variability versus external forcing factors like anthropogenic aerosols in driving the temperature changes. Specific...
- This National Science Foundation (NSF) Geosciences program grant (CFDA 47.050) provides $202,000 to fund research to understand the differences between observed and simulated patterns of tropical Pacific sea surface temperature (SST) warming. The 2-year project, beginning January 1, 2024, involves comparisons between climate models and a simplified Zebiak-Cane atmosphere-ocean model to identify the physical mechanisms causing the contrasting SST trend patterns. The research has implications...
- The National Science Foundation Division of Atmospheric and Geospace Sciences awarded The University of Chicago $942,543 on July 1, 2026, under the Geosciences program (CFDA 47.050) to investigate satellite-era trends in extratropical circulation extremes and their relationship to heat and precipitation extremes. The research combines observational data, theory, physics-based Earth system models, and artificial intelligence models to quantify mechanistic understanding of how atmospheric...
- The National Science Foundation (NSF) Division of Atmospheric and Geospace Sciences awarded a $556,334 Project Grant to the Regents of the University of California, doing business as the University of California, Berkeley. This grant is funded under the NSF Geosciences program (CFDA 47.050) to support research investigating the "distance effect" on Earth's climate, specifically how the annual cycle in Earth's distance from the Sun impacts the Pacific Ocean's warm pool and cold tongue...
- 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...
The National Science Foundation Division of Atmospheric and Geospace Sciences awarded the University of California, Los Angeles $609,211 on September 1, 2026, under the Geosciences program (CFDA 47.050) to investigate how extratropical climate forcings modulate tropical Pacific sea surface temperatures and influence global weather patterns. The project addresses an observational puzzle: the eastern Pacific Ocean has cooled over recent decades despite model projections of warming, yet this cooling significantly affects rainfall over the Southwest U.S. and weather patterns worldwide. Current Earth System Models fail to reproduce the observed cooling trend. The research tests the hypothesis that changes outside the tropics—including ocean variability around Antarctica, industrial aerosol emissions from the Northern Hemisphere middle latitudes, and the Antarctic ozone hole—drive tropical Pacific cooling through mechanisms that ESMs do not adequately capture. The work attributes model failure partly to the cold bias in the eastern equatorial Pacific and the double Intertropical Convergence Zone bias common across ESMs. The project will compare observations against existing ESM simulation archives and conduct new simulations using specialized configurations of the Community Earth System Model to test whether tropical mean basic state modulates the response to high-latitude forcing. Results are intended to improve near-term projections from Earth System Models and provide more reliable information for anticipating changes in U.S. weather patterns. The award funds work performed at UCLA's Los Angeles, California campus from September 1, 2026, through August 31, 2029.
