Cloud increment diagnostics, from a simulation of present‐day climate using a prognostic cloud scheme and from a case‐study of a mid‐latitude system, are used to highlight the variation in parametrized processes contributing to the creation and removal of cloud in the model. The diagnostics show that the initialization of the cloud fields away from cloud fractions of zero and one is a significant contribution to their evolution, drawing attention to the importance of the assumptions made when calculating those increments and highlighting a part of the cloud scheme where future development should be focused. © 2012 British Crown copyright, the Met Office.
