Models of clouds and atmospheric waves in the tropics

PDE and Applied Math Seminar

Speaker: Sam Stechmann, UCLA
Location: 2112 MSB
Start time: Wed, May 6 2009, 4:10PM

In the tropics, cloud systems are often organized by atmospheric waves with periods of 2 to 30 days, and these waves play an important role in the dynamics of global weather and climate. Despite the prominence of these waves in observations, their physical mechanisms are not understood well, and they are poorly represented in numerical models of the global atmosphere. In this talk I will present mathematical models that shed some light on these issues. The models include a blend of theory and numerics for new nonlinear PDE and multi-scale asymptotic models.
