Our research into cloud schemes focuses on how to represent clouds and cloud processes in numerical models which do not have sufficient resolution to resolve clouds. As both weather forecast or climate models fall into this category this research has high societal and academic relevance. | Our research into cloud schemes focuses on how to represent clouds and cloud processes in numerical models which do not have sufficient resolution to resolve clouds.

Overlaid are two PDFs from our scheme with slightly differing assumptions, | Here is an example of the total water histogram of a 55x55 km subdomain of the LES Simulation containing over 125000 grid cells.

- | With these tools we can now quantify many aspects of cloud parametrizations which were previously not measurable. Such aspects include how parametrization performance changes with model resolution, and breaking down the various error sources.
