- The National Science Foundation Division of Atmospheric and Geospace Sciences awarded $144,000 to the Regents of the University of Colorado on August 15, 2026, under the Geosciences program (CFDA 47.050) to conduct collaborative research linking lower-atmosphere weather to space weather using mesoscale modeling and artificial intelligence. The project will investigate how atmospheric gravity waves generated by meteorological events such as hurricanes and severe thunderstorms propagate upward...
- The National Science Foundation Division of Atmospheric and Geospace Sciences awarded the University of Texas at Arlington $236,000 on August 15, 2026, to investigate how atmospheric gravity waves generated by severe weather propagate into the ionosphere and produce traveling ionospheric disturbances. Under the Geosciences program, the project will conduct the first systematic examination of gravity wave evolution across more than 400 meteorological events, including hurricanes and severe...
The National Science Foundation Division of Atmospheric and Geospace Sciences awarded William Marsh Rice University $464,853 on August 15, 2026, under the Geosciences program (CFDA 47.050) to investigate how low-entropy plasma bubbles originating from magnetotail reconnection modulate prompt penetration electric fields during geomagnetic storms. The research combines observational validation with theoretical modeling to determine how these plasma bubbles—low-entropy flux tubes that transport energy Earthward at several hundred kilometers per second via the interchange instability—compete with external solar wind drivers in reshaping the equatorial ionosphere's electrodynamic state. By injecting low-entropy plasma into the inner magnetosphere, these bubbles alter ionospheric plasma distribution patterns that can disrupt satellite operations, high-frequency communications, navigation systems, and power grids. The project addresses a critical gap in space weather forecasting by accounting for high-speed dynamics that standard models have not incorporated, combining advanced numerical modeling with multi-instrument observational data to simulate the nonlinear magnetosphere-ionosphere coupling involving field-aligned currents, mass, and momentum exchange. Work is performed in Houston, Texas. The period of performance runs through July 31, 2029.
