Project Grant 2531488
- This $505,233 National Science Foundation award under the Geosciences program (CFDA 47.050) supports research at Indiana University to better understand the processes involved in transporting water vapor into the stratosphere. Specifically, the investigators will examine how sea surface temperatures impact cold point tropopause temperatures using reanalyses, numerical models, and COSMIC-II GPS data. They will analyze the atmospheric processes determining cold point temperatures and identify when...
- 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 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...
- This National Science Foundation Project Grant of $622,435 supports research into stratosphere-troposphere exchange of ozone and its changes over time. Funded under the Geosciences program within the NSF Division of Atmospheric and Geospace Sciences, the award will examine observational estimates of ozone exchange based on satellite data through 2025. The University of Washington will calculate ozone exchange using methodology accounting for tropical upwelling and extra-tropical downwelling....

The award supports collaborative research to investigate the role of atmospheric heat transport, radiation, and soil moisture on observed heatwaves, their representation in climate models, and future changes. Specifically, the project aims to: (i) analyze the physical mechanisms...
- 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...
- This National Science Foundation Project Grant of $267,901 will fund research into the response of the upper tropical Pacific Ocean to greenhouse gas forcing from August 15, 2022 through July 31, 2025. The award was made under the Geosciences program (CFDA 47.050), which supports basic research in the atmospheric, earth, and ocean sciences. Specifically, the grant will support a collaborative research effort examining how the temperature, currents, and thermal structure of the upper tropical...
- This National Science Foundation (NSF) Project Grant award under the Geosciences Program (CFDA 47.050) provides $796,213 to The Regents of the University of California, doing business as the University of California, Berkeley, to assess and understand the sensitivity of tropical orographic precipitation to climate variations. The research aims to further develop the theory of tropical orographic precipitation and investigate its response to environmental factors like wind speed, temperature, and...
- 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....
- This $707,741 project grant from the National Science Foundation Division of Atmospheric and Geospace Sciences Geosciences program (CFDA 47.050) will fund research into dynamical mechanisms for midlatitude-arctic interactions and associated weather extremes in a warming climate. The University of California, Los Angeles will examine several interrelated dynamical mechanisms through three tasks from April 15, 2023 to March 31, 2026. The researchers will analyze linkages between stratospheric...
This Project Grant award from the National Science Foundation (NSF) Geosciences Program (CFDA 47.050) provides $717,645.00 to the University of Washington to conduct research aimed at improving scientific understanding of the physical and dynamical processes that govern year-to-year changes in tropical cold point tropopause (CPT) temperature. The research team will analyze satellite observations, atmospheric reanalyses, and climate model simulations to investigate how tropical CPT temperature responds to warming in the tropical troposphere through competing radiative heating and dynamic cooling mechanisms. The project also examines the relationship between tropical CPT and stratospheric temperatures, which may be linked to the Brewer-Dobson circulation. The award period runs from Sep 15, 2025 to Aug 31, 2028 and will support the Ph.D. research of two graduate students, providing valuable training for the next generation of atmospheric scientists. The results of this study are expected to enhance understanding of how changes in CPT temperature can impact tropical rainfall, cyclones, and convection, thereby improving knowledge of regional weather extremes.
