Abstract
Space weather - the natural variability of near-Earth space - is a hazard to modern society, with the potential to affect satellite services and electricity supply. It is the fourth highest natural hazard risk on the Government's National Risk Register, alongside heatwaves and low temperatures. Arguably the greatest source of uncertainty is the substorm - an earthquake-like disruption of near-Earth space that eludes deterministic prediction. In this talk, I will show how substorm occurrence may be understood as a random walk towards an absorbing barrier, similar to the Gerstein-Mandelbrot model of neuron firing in the brain. I will discuss the limits of prediction and similarities to the space weather of Jupiter and Saturn.
All CS4 talks are free and refreshments will be provided from 3pm.
No registration is required. For videos of previous talks and details of future talks please visit: http://cs4southampton.wordpress.com
