Due to current conditions, we have decided to postpone the meeting to the 12 to 16 April 2021.

However, we have decided to maintain the hands-on workshop that was supposed to be organized on Monday (15 June) to define a common format for in- and outputs for Single-Column Models. This will occur via visio-conference probably on two afternoons (Monday and Friday in the week 15-19 June 2020) and participation will be on invitation. More information is given below.

The abstract submitted for this year will be kept and people will have the opportunity to modify them. The website for registration and submission of abstract will be kept open until next year.

Information on the common format workshop:
The High-Tune and DEPHY community (the French community working on development and evaluation of physical parameterization) has tested a format and would like to propose it to the community, and discuss possible modifications of this format in order to adapt to constraints of other modelling centers. This side workshop will be limited to 30 persons in order to be efficient and we encourage all the modeling groups to participate. If you are interested, please contact Frédéric Hourdin via email.

Theworkshop on Improvement and calibration of clouds in models will be held in Toulouse from 12 to 16 April 2021. The goal of this workshop is to discuss and share the latest improvements of atmospheric parameterizations for the representation of clouds with a focus on turbulence, convection, cloud, microphysics and radiation. This concerns any type of models: regional or global models with numerical weather prediction or climate applications.

In this workshop, we would like to have a strong component on the use of LES for the advancement of the representation of clouds with an emphasis on the following aspects:
observationsand LES for parameterization developments: systematic comparison of single-column model simulations to observations and LES on an ensemble of cases; parameterization-oriented diagnostics (invited speaker: R Neggers);
recentprogresses in cloud, turbulence, convection, microphysics parameterizations: new approaches, importance of coupling between parameterizations (invited speaker: C Rio);
cloudradiative effects: reference computation, cloud overlap and heterogeneity issues, new development in parameterization, coupling between radiation and other parameterizations (invited speaker: R Hogan);
strategyof tuning and in particular the use of new statistical tools to provide a process-oriented calibration of parameterizations, link with 3D tuning;
machinelearning for model improvement (invited speaker: T Schneider remotely);
thefuture for the representation of clouds in models.

The workshop is organized in the framework of the High-Tune project (http://www.umr-cnrm.fr/high-tune/) and follows, in the spirit, the 2017 Delft meeting on the future of cumulus convection and the 2019 Paracon conference. It will be organized around with only one plenary session with a mixture of invited and contributed presentations and poster sessions.

Two different 2-hour tutorials will be proposed:
oneon harnessing machine learning and the comparison of Single-Column Models and Large-Eddy Simulations for parameterisation development by Daniel Williamson;
oneon a renderer tool that allows to provide synthetic images based on Monte-Carlo computation of 3D LES field by Mesostar"(website)

The registration fee will be on the order of 300 Euros, which will include morning and afternoon coffee/tea breaks as well as daily lunches. It will also include the Icebreaker reception on Tuesday night and the conference dinner on Wednesday night.

A hands-on workshop will be organized on Monday (12 April) to define a common format for in- and outputs for Single-Column Models. The High-Tune and DEPHY community (the French community working on development and evaluation of physical parameterization) has tested a format and would like to propose it to the community, and discuss possible modifications of this format in order to adapt to constraints of other modelling centers. This side workshop will be limited to 30 persons in order to be efficient and we encourage all the modeling groups to participate. If you are interested, please contact via email frederic.hourdin@lmd.jussieu.fr.

The Grey Zone project 2 (website) will take advantage of the workshop to organize a one-day meeting on the 12th of April, 2021.

   
The workshop is postponed
to April 2021.
