A NetFAM/COST 722 workshop on cloud-covered boundary layer (CBL07)
will be arranged at March 12-14, 2007 in Toulouse, France. The aim of
the workshop is to join NWP modellers who develop methods for
forecasting fog and low clouds, shallow convection and moist
turbulence, to review the state of art, discuss the strategy, tasks
and plans. Main emphasis is in the fine-resolution models applied for
local forecast. Organisers of the workshop come from HIRLAM and ALADIN
communities, welcoming interested participants from all NWP
consortia. In a way, the workshop is a continuation of the NetFAM workshop on clouds and
convection, arranged in Tartu in January 2005. However, in the
present workshop deep convection will not be discussed.
Presentations of the following topics are welcome:
- Shallow convection and moist turbulence parametrizations, eddy diffusion mass flux schemes
- Interaction between surface processes, radiation and cloud microphysics in boundary layer
- Predicting clouds and fog in stable, neutral and unstable boundary layers
- Validation and case studies on PBL clouds
A keynote lecture on each of the topics is planned in addition to
contributions of the workshop participants.
The workshop will start in the morning of Monday, March the 12th, and
end around midday of Wednesday, March the 14th. Extendend abstracts of
the workshop presentations will be published as a workshop report and
the presentation files made available in web.

Participation and deadlines
To participate, please send an e-mail to the local organiser Eric
Bazile at meteo.fr, with a title of your (20 minute) presentation till
15 January 2007. Short abstracts for the workshop
site are welcome till 28th February, 2007. An extended abstract for
the workshop report should be provided after the workshop, till 15th
April 2007. It is also possible to participate without making a
presentation.
There is no registration fee in the workshop. Information about
accomodation in Toulouse can be found at the page of practical information. Support for
travel expenses is available for NetFAM and COST-722 members upon
request: please find the contact info at NetFAM and COST-722 web

Organisers
International organising committee: Eric Bazile (Meteo-France),
Sylvain Joffre (Finnish Meteorological Institute), Christine Lac
(Meteo-France), Dmitri Mironov (DWD), Hannu Savijärvi (University
of Helsinki).
The workshop is arranged in the framework of the Nordic Network on
Fine-scale Atmosperic Modelling (NetFAM), in cooperation with COST
action 722, developing short-range forecasting methods of fog,
visibility and low clouds.
The local organiser in Toulouse is Meteo
France and its International
conference centre
