Abstract
This chapter starts with an introduction to standard mass-flux parameterisations and closures for moist convection which are used in most large-scale models. The shortcomings of this approach will be discussed, especially for higher resolutions where standard assumptions such as quasi-equilibrium start to break down. New pathways that use a stochastic approach and are scale aware will be discussed. These will also allow to incorporate the effect of mesoscale organisation into parameterisations for moist convection.

- 1.
The precipitation area is not equal to the updraft area but for precipitating cumulus convection it is reasonable to assume that they are proportional to each other.
