Numerical Study of Coronal Mass Ejections, Shocks, and Turbulence: from Chromosphere to 1 AU.
(2014)
My dissertation focuses on one of the major source of destructive space weather: coronal mass ejections (CMEs). By helping develop and utilizing a new data-driven global MHD model: The Alfven Wave Solar Model (AWSoM) in ...
Diagnosing Energy Transfer in an Idealized Ocean-Atmosphere Model: A Frequency-Domain Approach
(2019)
Climate variability is an area of great interest. The ocean and atmosphere, two major components of the climate system, are inherently coupled, and there has been recent interest in deciphering whether oceanic and atmospheric ...
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 ...
Efficient Output-Based Adaptation Mechanics for High-Order Computational Fluid Dynamics Methods
(2018)
As numerical simulations are applied to more complex and large-scale problems, solution verification becomes increasingly important in ensuring accuracy of the computed results. In addition, although improvements in ...
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 ...
GNSS-R Remote Sensing of the Ocean: Surface Waves and Related Phenomena
(2016)
In this thesis, we explore several fundamental issues in GNSS-R remote sensing. Global Navigation Satellite System - Reflectometry (GNSS-R) is a relatively young remote sensing technique proposed to measure geophysical ...
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 ...
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 ...
