Luc Gerard: Geometrical aspects of sub-grid convective condensation and precipitation (CSU concept, closure, time evolution)
Luc Gerard: CSU and convergence towards the 'all-resolved' solution (triggering, academic example studies; open questions; conclusions, planning)

Moist physics

Laura Rontu: HARMONIE physics plans
Piet Termonia: Working group discussion
Neva Pristov: LACE physics plans

Outcomes, plans, final discussion

First Announcement (April 2012)

The purpose is to present ALARO-1 developments, plans and
to spread knowledge about the ALARO to a wider ALADIN/LACE/HARMONIE community.

Tentative program:


  •   Generalities
    •     introduction, an overview
    •     evaluation of ALARO-0 (local experiences, reporting the current implementations,...)
  •   ALARO-1 overview of current developments
    •     TOUCANS moist turbulence and diffusive transport,
    •     radiation,
    •     precipitations aspects
    •     convection: novelties in 3MT
  •   Discussion
    •     current status, open questions/problems, link with SURFEX, definition of ALARO-1
    •     future issues

Three part will be roughly split over three days, with some flexibility.

Starting Wednesday (13 June) morning, closing Friday (19 Feb) noon.
Detailed program will be provided later.

Please, confirm your participation to Neva ( and Piet (
(if possible before 25 April) and contact us for any question.
