This session explores advances and challenges in
convection-permitting atmospheric modelling: using the newest
generation of atmospheric models that allow for the explicit
treatment of convective processes (grid spacing ≤ 4 km).
Convection-permitting models (CPMs) are a rapidly growing area
of research and 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 feedback mechanisms and climate
change signals compared to models with parametrized deep
convection. CPMs offer a promising tool to better understand
fine-scale processes and provide critical information to
stakeholders, especially in areas affected by 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.
The session brings together numerical modellers, the
observational community, cloud physicists, forecasters and
CORDEX-FPS participants, with the aim of advancing understanding
of convection and high-resolution modelling 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. This session calls for papers on
state-of-the-art development and application of CPM activities,
including 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-scale phenomena (e.g. land-use change, land-ocean
contrasts, flow-orography interactions, urban-rural transitions,
aerosol effects, etc.). We welcome studies of past, present or
future climates, and CPM modelling across time scales.
Particular attention is given to extremes.
Other topics include, but are not limited to:
-- Model setup and parametrization, including sensitivity to
resolution and dynamics
-- Model evaluation and new evaluation metrics/methods
-- Ensemble-based approaches to quantify
predictability/uncertainty at convective scale
-- Physical understanding of the added value compared to coarser
models
-- Land-atmosphere coupling at convection-permitting scale
-- Application to climate studies
-- Tropical phenomena
-- Convection, energy balance and hydrological cycle
-- Lightning in CPMs
-- Teleconnection across scales
-- Novel high-resolution experiments
