Joint Seminar: Seasonally migrating convergence zones on Earth and other terrestrial planets

Idealized modeling studies have provided the basis for significant progress on our conceptual understanding of the fundamental dynamics of tropical circulations and associated convergence zones. Here, we study seasonally migrating convergence zones on an aquaplanet, i.e., over a uniform slab ocean of fixed depth, in a wide range of configurations and climates. In particular, we explore dynamical and thermodynamical mechanisms mediating the response of tropical precipitation to changes in surface heat capacity, planetary rotation rate and atmospheric long wave optical depth. Implications for observed monsoons on Earth and seasonal weather patterns on terrestrial planets will also be discussed.
