[RegCNET] Convection schemes and parameters

[Fiona TUMMON]

Hi there RegCMers!
  I'm doing some simulations  over southern Africa, using a domain
stretching from 0-40S, 0-55E, and was wondering if anyone has found that
a particular convection scheme works best over this region?  So far,
I've done some simple validations and it seems like either the Grell
with Fritsch + Chappel closure or the Anthes-Kuo schemes work best. 
Both of these schemes, however, lead to spots of strong convection which
don't appear to be realistic. Which parameters can I change and how to
avoid this?

 If anyone would be able to give me a word or two of advice I'd really
appreciate it!

Many thanks and best wishes for the festive season!

Fiona
