Data assimilation for extreme ionospheric events: observing system experiments of the September 26, 2011 geomagnetic storm
14 Apr 2016  Presentations  Contributor(s): Juan Durazo
As increasingly sophisticated ground and spacebased technological systems that depend on the nearEarth space environment are being built, vulnerabilities to variations in the ionosphere are also increasing. These vulnerabilities are especially prominent during extreme spaceweather events,...

Adaptive mesh refinement for storm surge modeling
03 Mar 2016  Presentations  Contributor(s): Marc Pierre Kjerland
Coastal inundation such as storm surge is a major concern for many of the world's population centers, and recent disasters such as Hurricane Sandy and Typhoon Haiyan highlight the growing risks of climate change. Numerical simulation of storm surge can be challenging due to the large spatial...

Local and nonlocal mechanisms of Arctic warming
25 Feb 2016  Presentations  Contributor(s): Vladimir Alexeev
Polar amplification (PA) is a prominent feature of currently observed and predicted future climate change suggested by both observations and models. We will discuss several PA mechanisms and feedbacks in the ocean and the atmosphere suggested by different researchers and connect it to the real...

New averaging results motivated by climate models: fat tails, oscillations, and tipping
10 Dec 2015  Presentations  Contributor(s): Rachel Kuske
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  Contributor(s): Jonah BlochJohnson
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...

Modelling the Marginal Ice Zone
23 Nov 2015  Presentations  Contributor(s): Luke Bennetts
The marginal ice zone (MIZ) is the 10s to 100s of kilometres of partially icecovered ocean, which sits between the open ocean and the quasicontinuous ice cover. It’s a highly dynamic region, where open ocean wave processes impact the ice cover, and it’s becoming larger and more...

Where's the Math in Climate Science?
09 Nov 2015  Presentations  Contributor(s): Christopher KRT Jones
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...

Hybrid EnKF and Particle Filter: Lagrangian DA and Parameter Estimation
