1. Our name & the web page

From WG4 we went to the deep working group but this confused many. I am happy for suggestions but unless I hear otherwise from now I plan to refer to this group as:

GCSS Precipitating Convective Cloud Systems working group - shortened to GCSS PCCS.

I have updated the front page of the web (www.convection.info) to reflect this. I have also updated the news section to include this message. Please let me know if you feel other aspects of the page should be updated.

2. Case 5 TWP simulations progress

Two papers describing multi model comparisons are progressing well. One paper will describe NWP and climate models and another will describe CRMs and SCMs. Many thanks to Martin Willett, Steve Woolnough and all the participants for their on-going work into this.

Many plots are available from GCSS PCCS web page from both these areas of work (www.convection.info)

3. Debate on future work

It is timely now to consider the direction and further collaborative work for the PCCS. I am interested in peoples views on what this group should do next. Specifically:

Do we want to do more model comparisons, or if not, then what should we do as a group?

• If we should do more model comparisons should it still involve NWP (climate as NWP), SCMs and CRMs?
• What science issues should we focus our attention on next?
• What Case studies can we use to do this?
• Who might lead any suggested study?
• Are there other groups (e.g. AMMA, ARM, SPARC) we should collaborate on our future work?
• Any other thoughts/views?

I am happy for responses to be sent to [jon.petch@metoffice.com] me and I will summarise. Or concise discussion points can be made to the whole maillist. I will try to wrap this up and move forward in about a month.
