The 9th June case.

Damian Wilson

This is a convective case, with widespread showers formed from weak convection. The radar returns clearly have a melting layer, which suggests graupel formation and strong updraughts do not exist in this case.

Observational Data

Radar data, from the Chilbolton radar, for this event can be found via the University of Reading Radar Group website. Aircraft data should follow soon.

Model simulation

The model requires a good prediction of convection as well as large-scale microphysics. It is difficult to assess the large-scale parameterizations with convective cases: There is a representivity problem and much of the condensate is only around within the convective regions.
