Despite its importance, the MJO is not predicted by current weather models. Understanding the MJO presents a challenge to atmospheric modeling, but promises new insights into the complex system that is our weather.
Samuel Stechmann, mathematics professor at the University of Wisconsin, will describe a new model of the MJO at a lecture on Thursday, January 10. The talk, titled "The skeleton of the Madden-Julian oscillation: a nonlinear oscillator model," will describe joint research with Andrew Majda of the Courant Institute of Mathematical Sciences at NYU. The work will appear in the journal Nonlinearity.
Was Hurricane Sandy an extreme weather event or due to a changing climate?
Important climate issues, such as sea level rise, snow-cap cover estimates, glacier dynamics, greenhouse gas estimates, global temperature, and whether we are experiencing a weather event (an unusually hot summer) or a climate phenomenon (global rise in temperature), depend on the establishment of an unambiguous trend. Researchers at the University of Arizona, Juan M. Restrepo, Darin Comeau, Shankar Venkataramani, and Hermann Flaschka, address the shortcomings or inapplicability of conventional statistical methods to capture a trend in these and other geoscience problems.
On Friday, January 11, Juan M. Restrepo, group leader of the Uncertainty Quantification Group and the facult
