Open for individual contributions (will be finalized on 12 - 13 July during the ICMW)
12:15 - 14:00 Discussion along the following questions:

-Are LES-models or cloud resolving models useful tools to develop convection shcemes for large scale models?

- Is dry convection important?

- Which complexity do we need for teh micro-physical processes within convective clouds?

- What is the contribution of deep convection to the radiation balance? Is 3D modeling of radiation needed in connection with deep convection?

- Which role does convection play in high latitudes?

- Which convection shcemes are adequate for specific problems? (Energetic, formation of precipitation, vertical tracer transport...)

- Do we have quality measures and assurance (intercomparison..)?

- Which information / data are required to adequately describe convection?

The mini workshop will close at 14:00. We will then have time to eat and start our sightseeing tour at about 15:30. Further details on this will be posted soon. On Wednesday evening, we will join the Workshop dinner.
