Theworkshop on Improvement and calibration of clouds in models will be held in Toulouse from 16 to 19 June 2020. 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.
observations and LES for parameterization developments: systematic comparison of single-column model simulations
to observations and LES on an ensemble of cases; parameterization-oriented diagnostics;
recent progresses in cloud, turbulence, convection, microphysics parameterizations: new approaches, importance of
coupling between parameterizations;
cloud radiative effects: reference computation, cloud overlap and heterogeneity issues, new development in
parameterization, coupling between radiation and other parameterizations;
strategy of tuning and in particular the use of new statistical tools to provide a process-oriented calibration of
parameterizations, link with 3D tuning;
machine learning for model improvement;
the future for the representation of clouds in models.
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:
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.
A 2 hour tutorial on harnessing machine learning and the comparison of Single-Column Models and Large-Eddy Simulations for parameterisation development wil be proposed by Daniel Williamson.
The registration fee will be on the order of 250 Euros, which will include morning and afternoon tea as well as daily
lunches. It will also include the Icebreaker reception on Tuesday night and the conference dinner on Thursday night.
A hands-on workshop will be organized on Monday (15 June) 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 firstname.lastname@example.org.
