  1. Modelling the Microphysical Sensitivities of Storm Dynamics Tim Baker Supervisors: Peter Knippertz & Alan Blyth

  2. Background • Graduated from University of Leeds 2010 with BSc in Environmental Science. • Dissertation: Modelling air flow over partially forested hillsides. • Summer 2010: Working for Ian Brooks doing data analysis and quality control.

  3. DIAMET • Part of the DIAMET (DIAbatic influence on Mesoscale structures in ExTratropical storms) project. • Consortium of Universities of Leeds, Manchester, Reading, East Anglia with NCAS and NCEO along with the Met Office as project partners. • Aims: Increase understanding and predictability of mesoscale features within extratropical cyclones

  4. Why study this? • Extratropical storms cause large scale disruption and damage to people and property. • Can forecast well on the synoptic scale but precise locations and timings of mesoscale structures are far less certain. • Improve microphysical parameterisation schemes for NWP models.

  5. Plan • Use case studies which exhibit mesoscale features where microphysics may be important in their formation. • Collect data using the FAAM BAe-146 aircraft including dropsondes, winds, turbulence and microphysics. • WRF modelling with different microphysics schemes and compare to UM results.
