Abstract

Specific features that distinguish high altitude cirrus from warm and mixed phase clouds are reviewed, along with observational evidence in support of these features. Implications for statistical cloud schemes based on probability distributions of total water are highlighted. A prognostic cloud scheme for non-convective cirrus formed by homogeneous freezing of supercooled aerosols is developed, predicting relative humidity fields and ice cloud properties in good agreement with observations. Uncertainties and future extensions of the cloud scheme are summarised.
