Description
This thesis shows analyses of mixing and transport patterns associated with Hurricane Katrina as it hit the United States in August of 2005. Specifically, by applying atmospheric velocity information from the Weather Research and Forecasting System, finite-time Lyapunov exponents have been computed and the Lagrangian Coherent Structures have been identified. The chaotic dynamics of material transport induced by the hurricane are results from these structures within the flow. Boundaries of the coherent structures are highlighted by the FTLE field. Individual particle transport within the hurricane is affected by the location of these boundaries. In addition to idealized fluid particles, we also studied inertial particles which have finite size and inertia. Basing on established Maxey-Riley equations of the dynamics of particles of finite size, we obtain a reduced equation governing the position process. Using methods derived from computer graphics, we identify maximizers of the FTLE field. Following and applying these ideas, we analyze the dynamics of inertial particle transport within Hurricane Katrina, through comparison of trajectories of dierent sized particles and by pinpointing the location of the Lagrangian Coherent Structures.

Description
Meteorology is an uncommon term rarely resonating through elementary classrooms. However, it is a concept found in both fourth and sixth grade Arizona science standards. As issues involving the environment are becoming more pertinent, it is important to study and understand atmospheric processes along with fulfilling the standards for each grade level. This thesis project teaches the practical skills of weather map reading and weather forecasting through the creation and execution of an after school lesson with the aide of seven teen assistants.

Description
Summer temperatures in Arizona are some of the highest in the nation. Arizona also ranks within the top ten states for percentage of homelessness per capita (Wisevoter, 2023). Extreme heat poses a threat to the rising homeless population in Phoenix, Arizona, as it causes severe dehydration, which can lead to potentially fatal heat-related illnesses like heat stroke. Sufficient hydration and lowering body temperature are the first paths of treatment for such illnesses. Thus, there is a critical need for water and heat-relief for homeless individuals in the Phoenix community. This paper responds to this crisis by proposing The Hydro-Drive Project, an incentivized, donation-based charity that provides cold water storage solutions to the homeless community in Phoenix. Using a three-pronged approach, The Hydro-Drive Project will collect, sanitize, and distribute insulated water bottles to homeless individuals in Phoenix. Providing insulated water bottles to persons experiencing homelessness can provide both hydration and coolness, which in turn, can help prevent heat-related illnesses. This paper also outlines a comprehensive plan for securing grant funding and establishing partnerships with like-minded organizations, as well as other elements necessary to ensure the success and sustainability of the program such as participant recruitment strategies, success and impact measures, project limitations, budget, and sustainability. Overall, The Hydro-Drive Project is an innovative response to a critical issue in the Phoenix community that requires grant funding and input from partnerships.
