Incorporating Spatio-Temporal Convection Effects in Classical Snowball Earth Models

This project will look at adding spatial diffusion to the classical ice-albedo feedback models of Budyko, Sellers and Jormungand. In particular we will look at a model by North, and another by Widiasih, which examine the effects of incorporating heat convection via diffusion across latitudes in the location and temperature (and stability) of polar ice caps. Furthermore, the models studied will be implemented numerically to visualise results.

With a strong interest in the natural world and its complexities, Elizabeth has pursued a Bachelor of Science with majors in mathematics and physics at The University of Sydney. As such, her interests lie in applied mathematics, with a focus on mathematical modelling. In the future, she hopes to apply this knowledge to a career in meteorology. In semester 2 of 2020, Elizabeth was supervised by Dr. Robert Marangell for a project titled “Mathematical Modelling of Snowball Earth Events” in which the Budyko-Sellers energy balance model was studied.
