סמינר בחוג לגיאופיזיקה: Convective rotating shallow water: a "low-cost" tool for understanding dynamical influence of diabatic effects upon large-scale atmospheric motions
Prof. Vladimir Tseitline (Zeitlin), P. et M. Curie University/Ecole Normale Superieure, Paris
I will show how to introduce convective fluxes in a self-consistent way in rotating shallow models which follow from vertical averaging of the primitive equations in pressure coordinates. I will demonstrate that the model reproduces, at low cost, the characteristic features of moist baroclinic instability, moist instabilities of hurricane-like vortices and salient features of their life-cycle, and also the observed structure of Mars' polar vortex, taking into account the gas-solid phase transition of CO2.
