An ICTP meeting in person

Organized convective systems are often responsible for high impact precipitation extremes, and changes in convective organization have the potential to amplify or dampen future climate change. This workshop will examine our present knowledge of convective organization in models and observations.

Convective organization is of special relevance to both weather and climate. Despite representing only 20% of cloud systems, mesoscale organised convective systems have been shown to provide over 80% of surface precipitation in the West Africa monsoon. Convective organised systems are also frequently associated with precipitation extremes.

Changes in convective organisation and clustering in future may represent a feedback on climate that is poorly represented, or even absent, in current generation models. Present efforts to improve our understanding include observational studies, highly idealized models, limited-area convective permitting models, and global models which use parameterizations or are operating at convective permitting resolutions in state-of-the-art projects such as Nextgems.

This workshop aims to bring together all these tools to assess our present understanding of convective organization.

  • Convective self-aggregation in idealized experiments
  • Precipitation extremes associated with organized convection
  • Using idealized models to improve our understanding of aggregation
  • How can we better use observations?
  • Impact of aggregation and organization changing on climate sensitivity
  • Aggregation in global cloud resolving model experiments
