Large eddy / cloud resolvingmodel (LEM/CRM)Tom AllenBen ShipwayLeeds, Reading,Aberystwyth, ImperialCollege, DurhamReading, Leeds,Imperial College,UMIST andAberystwyth1.5 day workshop on LEM/CRM and BLASIUSusage and development held at Met Office, June2005. This led to software generated in theuniversities being incorporated in the CRMduring 2006.3. Orographic dragparametrizationStuart WebsterLeedsHelen Wells (MetOffice) PhD withAndrew RossExcellent progress on understanding drag oncomplex terrain and processes which controlmountain wake development.4. Turbulent flow over hills Simon Vosper,Andy BrownLeedsAndrew Ross, StephenMobbs,Collaborative work in this area has led todevelopments to the BLASIUS code (forestcanopies and turbulence closure schemes).MetOffice will contribute to new field campaign onIsle of Arran (autumn 2006) throughobservations and BLASIUS modelling support.The latter will involve tests of new pressuresolver.
5. Hazardous winds inorographic regionsSimon VosperLeedsStephen MobbsRecent collaborative field campaign aimed atstudying rotors downwind of Pennines.Collaborative participation (with BAe146 aircraft)in T-REX took place in March-April 2006.Resulting observational and modelling activitieswill contribute to development of the UM.6. Chemical and AerosolTransport in ConvectiveCloudsJon PetchLeedsGerry Devine PhD(CASE) with DougParker and Ken CarslawInvestigated tracer transport in convection andincluded a basic sulphur cycle in the CRM.7. Modelling of tropicalconvection (e.g. GCSS deepconvection WG case 5)Jon Petch, SteveDerbyshireCGAM, ReadingJulia Slingo, SteveWoolnoughOngoing evaluation of model performance.May also evolve into collaboration on a NERCconsortium bid to simulate tropical convectionover large domains, if that bid is successful.8.
