An ICTP Hybrid Meeting
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.
Following on from the 2nd cloud organisation workshop (WCO2) that took place in Utrecht in 2022, this workshop aims to bring together all these tools to assess our present understanding of convective organization.

Call for Contributed Abstracts: All applicants are encouraged to submit an abstract for a poster presentation and/or a contributed talk. Abstract templates are available below for download.
Program: All participants are encouraged to contribute by either a poster or a talk (approximately 15 min + discussion). These contributions will be broadly grouped into the themes by the program organisers. Please indicate when applying your preference for a poster or oral presentation if you have one.
Grants: A limited number of grants are available to support the attendance of selected participants, with priority given to participants from developing countries. There is no registration fee.
Information: Some information regarding the ICTP campus can be found here and transportation here.
The workshop dinner: A group buffet style dinner will be held on the Wednesday evening during the event. We hope you will all join and enjoy the Trieste weather by the sea.
The deadline for applicants requesting financial and/or visa support is 29 May 2023; the deadline for all other applicants is 12 June 2023.
