Dr Steve Derbyshire
Steve leads a research and development team working on flow over topography.
Steve has now returned to the scientific interest (which he has had since his PhD) in the impacts and representation of flow over topography.
The group has a wide brief, which includes involvement in projects on topics as varied as gravity-wave drag, fog, tropical cyclones and rainfall enhancement over hills.
Steve also leads a Process Evaluation Group on conservation properties in the UM.
Steve's PhD was a collaboration between Cambridge University and the Met Office (Julian Hunt and Paul Mason) on 'Modelling the Nocturnal Boundary Layer'. He used large-eddy simulation and theoretical analysis to develop and extend our understanding of the stably-stratified atmospheric boundary layer and its governing parameters.
Following his PhD, Steve led the rewriting of the Met Office Large Eddy Model so that it could be used for both boundary layer and deep convection problems.
Steve then spent six years (1991-7) conducting observationally based research at the Met Office Research Unit, Cardington, leading a number of experiments and detachments, including studying nocturnal flow over the Llanthony valley using a tethered-balloon-based measurement system.
In 1997 Steve returned to Met Office in Bracknell to take up responsibilities for moist atmospheric convection. The European Cloud-Systems (EUROCS) collaboration led to an influential paper on convection sensitivity to environmental humidity, based on intercomparison of Cloud-Resolving and Single-Column models.
From 2003-13 Steve led the team responsible for convection parametrization in the Unified Model and brought forward a number of incremental improvements, as well as testing new types of convection representation.
Steve has supervised four PhD students, on both boundary-layer and convection topics (Andrew Maguire, Bernard Claxton, John Holden and Laura Davies).
