Forum Summary:
Convective-permitting modeling (CPM) yields step improvements
in the physical representation of precipitation, as has been
demonstrated in applications of numerical weather prediction
and climate modeling. While CPM has been used in the context
of historical climate simulations and climate change
projections, its application to the sub-seasonal to seasonal
(S2S) forecast timescale (weeks to months) is
comparatively underexplored. New, long-term S2S reforecast
products have recently been generated from operational global
forecast models, analogous to CMIP models used for climate
change projection. It is now technically possible to
dynamically downscale these reforecast data to CPM scale, to
assess potential improvement in S2S forecast skill and create
new S2S forecast metrics for extreme events. The Coordinated
Regional Ensemble Downscaling Experiment (CORDEX) provides an
existing robust community framework that can be leveraged to
dynamically downscale S2S reforecast data, in a globally
unified way.
Within this community discussion, we will first present
several overview presentations to the topic by the forum
facilitators. This will be followed by an open community
discussion and collective identification of research
priorities and action items proceeding forward.
The goal of this event is to foment a working group
that will lead to the development of white papers, proposals,
and community meetings on the topic of convective-permitting
S2S forecasting.
