Parallel Worlds with Extra Non-Hydrostaticness

I would like to thank my supervisor Dr Robert Plant for all of his advice and support during this project, and for performing all of the model runs for me. I would also like to thank Laura Davies for pointing out a few silly mistakes I made when working with the model output, thus preventing my nervous breakdown. Thanks also go to my parents for supporting me throughout the course. Representation of cumulus convection in circulation models is an ongoing problem. The traditional method is a parameterization, but this field is still far from providing an accurate scheme with sensible assumptions. Cloud resolving models (CRMs) offer a more realistic simulation of convective systems, but current computing capabilities prevent their use on a global scale. There are various systems that have been suggested to allow the use of cloud resolving models in a system covering the whole globe without requiring the computing power needed to run a global CRM. One such approach, known as DARE, was proposed by Kuang et al. (2005), in which the hydrostaticness of the system was reduced. Rescaling the system to make it more non-hydrostatic increases the scale of convective cells, allowing the
