ENSO in a warming climate

Mathieu Richaud, Department of Earth and Environmental Sciences, Fresno State University

Topic: ENSO, warming climate, climate change
Course type: Introductory undergraduate course

Description

First, I would like to model ENSO using the flow of water/heat produced by the internal Kelvin and Rossby waves traveling through the Pacific Ocean. Second, I would like to be able to predict its long-term change over hundreds of years as the climate warms (i.e., more El Nino-like or more La Nina-like?).

Learning Goals or Outcomes

1) Full grasp of the concept of ENSO being a coupled atmosphere-ocean system, where the ocean and the atmosphere influence each other.
2) Full understanding of the feedback concept.
3) Better understanding of what numerical models are and can be used to understanding climatic events.

How would you assess whether those goals have been met?

Assessment by writing a summary paper of the model building and of the results.
