Dear colleagues,

we would like to invite submission of abstracts to our session on 
convection-permitting atmospheric modelling at the 2018 EGU General 
Assembly (Vienna, 8‒13 April 2018):

CL5.07 Convection-permitting atmospheric modelling 
<http://meetingorganizer.copernicus.org/EGU2018/session/26438/>

Session description:
This session explores recent advances in convection-permitting 
atmospheric modelling, with the newest generation of atmospheric models 
that allow for the explicit treatment of convection: regional and global 
models, variable resolution models (e.g. ICON, MPAS), and models using 
super-parametrizations.

Convection-permitting models (CPMs) have been shown to improve both the 
diurnal convective cycle and the representation of convective 
precipitation, particularly extremes. Furthermore, CPMs often exhibit 
important differences in climate-feedback mechanisms and climate change 
signals compared to models with parametrized deep convection. CPMs offer 
a promising tool to provide critical information to decision makers and 
stakeholders, especially in areas at risk of convective extremes and 
mountainous regions, and have thus sparked wider interest in their 
applications and development, for example the CORDEX Flagship Pilot 
Study (FPS) on convective phenomena over Europe and the Mediterranean.

This session also brings together the observational community, cloud 
physicists, numerical modellers, forecasters and CORDEX-FPS 
participants, with the aim of advancing understanding of convection in 
general (including convective storm life cycle and convective 
organization) with new modelling and statistical observation approaches. 
Contributions on new high-resolution/sub-daily observational datasets, 
and their application to CPM evaluation, are particularly welcome. The 
session also encourages the examination of interactions between 
convection and other atmospheric phenomena (e.g. boundary layers, cloud 
physics, radiation), as well as CPM investigations of local to regional 
circulations (e.g. land-ocean contrasts, flow-orography interactions, 
urban-rural transitions).

Other topics include, but are not limited to:
- model setup and parametrization
- model evaluation and new evaluation metrics/methods
- ensemble-based approaches to quantify uncertainties at convective scale
- physical understanding of the added value compared to coarser models
- land-use changes at convection-permitting scale
- application to climate studies for short and long-term simulations.

Particular attention is given to the representation of extremes.

The deadline for abstract submission is Wednesday, January 10th 2018 
@1300CET. The deadline for application for financial support is Friday, 
December 1st 2017.

Please forward this announcement to anyone who may have interest in the 
session. We look forward to receiving your contribution and seeing you 
in Vienna.

On behalf of the conveners,
Edmund.
