  1. 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.

  2. 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. 

  3. 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.

  4. Vegetation patterns in mathematical models, and vegetation patterns in Horn of Africa

    21 Apr 2016 | Presentations

    Visually striking large-scale spatial patterns of vegetation have been observed in semi-arid regions in the Americas, Africa and Australia. These have led to suggestions by theoretical ecologists that certain characteristics of the patterns may serve as early-warning signs of desertification....

  6. 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 non-autonomous multiple scale systems with oscillatory forcing.  These types of systems appear in a variety of higher dimensional...

  7. 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...

  8. Where's the Math in Climate Science?

    09 Nov 2015 | Presentations

    Abstract: Climate science is dominated by the use of large-scale 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...

  9. Tipping points and power cuts

    18 Jun 2015 | Presentations

  10. Who, or what, will tip the big climate models?

  11. 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...

  12. Midwest Mathematics and Climate Conference - Day 2 Afternoon Session

    12 May 2015 | Presentations

    Charles Jackson, University of Texas, AustinDual-state Behavior of the Community Climate System ModelIce age climate between 80,000 and 11,000 years ago experienced abrupt (< 10 year) global-scale climate transitions every few thousand years. Evidence and theory suggests such behavior may be...
