Abstract: 

Outline

1. Satellite/reanalysis views of tropical clouds (MODIS, ISCCP, Bony et al.)
2. Basics: Moist thermodynamics, buoyancy, CAPE, mixing diagrams, conditional/slice instability
3. Impact of clouds on large scale fields ($ Q_1, $ $ Q_2 $, mass flux models)
4. Equilibrium coupling of shallow and deep convection: one cell model
5. Entrainment, detrainment, buoyancy sorting 6. What controls convective cloud top height?
