Modelling weakly coupled nonlinear oscillators: volcanism and glacial cycles
Jonathan Burley
(Department of Earth Science, University of Oxford)
Abstract
This talk will be a geophysicist's view on the emerging properties of a numerical model representing the Earth's climate and volcanic activity over the past million years.
The model contains a 2D ice sheet (Glen's Law solved with a semi-implicit scheme), an energy balance for the atmosphere and planet surface (explicit), and an ODE for the time evolution of CO2 (explicit).
The dependencies between these models generate behaviour similar to weakly coupled nonlinear oscillators.
