Interactions between Heliospheric and Ionospheric Plasma in Geospace
(2022)
The Sun interacts with the Earth through electromagnetic radiation, gravitationally, and through the solar wind. The solar wind carrying the Sun’s magnetic field interacts with the Earth’s magnetosphere and drives the ...
Characterizing Heliospheric and Interstellar Interactions Using Pickup Ion Measurements
(2022)
The Heliosphere, orbiting the galactic center of the Milky Way, is a plasma bubble carved out of the Local Interstellar Medium (LISM) by the Sun's dynamic and magnetic influence. Its relative motion creates a steady inflow ...
Dynamics of the Jovian Magnetosphere: Combining Insights from Global MHD Simulations and In Situ Measurements From the Juno Spacecraft
(2021)
Unlike the terrestrial magnetosphere, which responds strongly to changes in the solar wind and interplanetary magnetic field, Jupiter's magnetosphere depends largely on internal processes related to its strong planetary ...
New Applications of Satellite-Measured Tropical Cyclone Wind Speeds
(2021)
Major hurricanes are becoming more frequent due to climate change and the warming of the oceans. Now more than ever, the ability to model hurricanes accurately and provide advanced warning to affected areas is crucial. ...
Understanding the Impacts of Mesosphere and Lower Thermosphere on Thermospheric Dynamics and Composition
(2021)
The Earth’s Ionosphere and Thermosphere (IT) is a highly dynamic system persistently driven by variable forcings both from above (Solar EUV and the magnetosphere) and the lower atmosphere. The forcing from below accounts ...
Contribution of Crevasse Advection and Mixed Mode Calving to Glacier Dynamics
(2021)
Modeling of the climate system including, but not limited to, atmospheric dynamics, ocean dynamics, and ice dynamics, is one of the crucial scientific problems of the 21st century. This work focuses on modeling of iceberg ...
Europa's Plasma Interaction with Jupiter's Magnetosphere: Characterizing Variability of the Plasma Interaction with Multi-Fluid MHD Simulations
(2021)
Europa, one of Jupiter’s Galilean moons, is embedded in the region of space dominated by Jupiter’s magnetic field known as Jupiter’s magnetosphere. The interaction of Jupiter’s magnetospheric plasma and magnetic field with ...
A Data-Driven Understanding of Plasma Transport in Saturn's Magnetic Environment
(2020)
In 2004 the Cassini-Huygens mission arrived at Saturn. As the first ever Saturn
orbiter, Cassini collected data reaching from the largest moon, Titan, at 20 Saturn
radii (Rs), to the atmosphere during its death plunge in ...
Global Hall Magnetohydrodynamics and Coupled Fluid-Kinetic Simulations of Mercury's Dayside Magnetopause Dynamics
(2023)
Mercury possesses a miniature yet dynamic magnetosphere driven primarily by the solar wind through magnetic reconnection. Because Mercury is 60% closer to the Sun than Earth, its magnetosphere routinely experiences stronger ...
Improving Barotropic Tide Modeling in MPAS-Ocean and Estimating Changes in Future Tides
(2023)
Modeling the ocean is critical for understanding both present and future risks posed by climate change on coastal communities. Ocean tides in these regions will continue to change over the following decades, yet tides are ...
