Deriving the SWM Lecture 3: Barotropic Vorticity Equations
04 May 2016  Presentations
This lecture develops the barotropic vorticity equations for the shallow water model. This is background lecture 2.1C in the Mathematics of Climate Modelling course.

Deriving the SWM Lecture 2: Stream Functions for Velocity Fields
04 May 2016  Presentations
This lecture develops the formulation of the stream function for the velocity field of the shallow water equation. his is the second in a series of short lectures on deriving the shallow water model, given by Chris Jones in 2013.

Deriving the SWM Lecture 1: Conservation of Potential Vorticity
04 May 2016  Presentations
This lecture develops the conservation equation for potential vorticity in the shallow water model.

Vegetation patterns in mathematical models, and vegetation patterns in Horn of Africa
21 Apr 2016  Presentations
Visually striking largescale spatial patterns of vegetation have been observed in semiarid regions in the Americas, Africa and Australia. These have led to suggestions by theoretical ecologists that certain characteristics of the patterns may serve as earlywarning signs of desertification....

New averaging results motivated by climate models: fat tails, oscillations, and tipping
10 Dec 2015  Presentations
We review recent results where new averaging approaches are developed and applied in the context of systems with multiple time scales and fat tails and in nonautonomous multiple scale systems with oscillatory forcing. These types of systems appear in a variety of higher dimensional...

Global Warming Could Be Nonlinear
23 Nov 2015  Presentations
It is widely acknowledged that many components of the Earth's climate system exhibit nonlinear behavior when forced, with examples ranging from ice sheets to ocean circulations to savanna. These changes, as profound as they are, are not expected to greatly impact global climate, as...

Where's the Math in Climate Science?
09 Nov 2015  Presentations
Abstract: Climate science is dominated by the use of largescale models, of which there are only 30 or so around the world. It might then seem that the need for mathematics is limited to areas that directly support the operation of such models. I will explain, by digging into the way the models...

ICMS Tipping Points: Fundamentals and Applications
13 Jun 2015  Workshops
Objectives: This workshop (September, 2013) brings together mathematicians and statisticians, whose research expertise is relevant to investigating threshold behaviour in complex environmental systems, with the climate scientists and ecologists who exploit mathematical modelling in their research...

Midwest Mathematics and Climate Conference  Day 2 Afternoon Session
12 May 2015  Presentations
Charles Jackson, University of Texas, AustinDualstate Behavior of the Community Climate System ModelIce age climate between 80,000 and 11,000 years ago experienced abrupt (< 10 year) globalscale climate transitions every few thousand years. Evidence and theory suggests such behavior may be...

Midwest Mathematics and Climate Conference  Day 2 Morning Session
12 May 2015  Presentations
Juan Restrepo, Oregon State UniversityData AssimilationAccounting for uncertainties has led us to alter our expectations of what is predictable and how such predictions compare to nature. A significant effort, in recent years, has been placed on creating new uncertainty quantification techniques,...
