Mathematics of Interacting Climate Processes
February 11 - 13


What we can learn about Snowball Earth using simple math
Dorian Abbot, University of Chicago

I will explain applications of simple math problems worked out by Fourier, Stokes, and Stefan (as well as more recent work) to Snowball earth.

How Republican is the Ocean?
William Dewar, Florida State University

An operant question for climate models is what are the mechanics of the fundamentally non-conservative (i.e. democratic) processes in the ocean. I will discuss some recent thoughts on the biogenic mixing of the ocean, and the role of topography in decelerating the oceanic large scale flow.

Sea Ice Modeling for Climate Applications
Marika Holland, NCAR

I will be discussing sea ice modeling in the context of the global climate system. Feedbacks that modify the sea ice response to forcing perturbations and how these influence the stability of the Arctic sea ice cover will be covered

Climates of Deep Time and What They May Tell Us About Earth's Future Climate
Jeff Kiehl, NCAR

Earth's warm climates of the deep past provide perhaps the best picture of how our climate system works under elevated greenhouse forcing. We will explore Earth's deep past and consider how Earth's past may provide a window into Earth's future.

Physical-biological Interactions in the Upper Ocean
Amala Mahadevan, Boston University

We examine some of the different dynamical processes that underlie phytoplankton productivity in various oceanic settings. The complexity of the physical-biological interactions makes it difficult to assess how changing climatic conditions would affect the carbon cycle.

Climate Change Over the Last 65 Million Years
Pamela Martin, University of Chicago

Reconstruction, assimilation of paleoclimate data, and some outstanding climate problems in the Cenozoic.

Modelling Interactions between Weather and Climate
Adam Monahan, University of Victoria

The ocean and atmosphere interact across a broad range of space and time scales; when dealing with climate variability, weather processes cannot be ignored. This talk discusses a mathematicak framework for building (generally stochastic) climate models from coupled weather-climate systems.

Climate Science at NCAR
Douglas Nychka, NCAR

This talk will give an overview of the Earth's climate system and describe the interaction between the physical models for the many different process that contribute to climate and how this knowledge is translated into numerical and discrete models.

Reduced Models of Large-Scale Ocean Circulation
Roger Samelson, Oregon State University

Most of our theoretical understanding of the large-scale ocean circulation is based on reduced sets of equations, which are motivated by a priori assumptions on the scales of motion. I will briefly review this approach and discuss an example relating to the middle cell of the meridional overturning circulation, which is believed to have a significant role in the climate system.

Modeling Sea-Ice Mechanics
Deborah Sulsky, University of New Mexico

Analysis of satellite observations of sea ice has led to a wealth of new data about ice motion and deformation. These observations form the basis for a new sea-ice rheology that directly accounts for leads and shows promise for more accurately representing observed processes
