Description
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.
