Note: this meeting is the virtual version of the meeting originally planned for May 2020, which, due to the coronavirus pandemic, had to be postponed.

Today, the modelling of Earth's atmosphere is performed at such high spatio-temporal resolution, that it sometimes is difficult to distinguish observations from models. However, fundamental understanding of what drives pattern-formation in the cloud fields and its effect on precipitation and the cloud feedback remain to be uncovered. Extreme precipitation events - representing an immediate threat to humans and infrastructure - are still not well understood, but often related to the formation of cloud clusters. The basic mechanism underlying tropical cloud clustering over the ocean, leading to the Madden-Julian Oscillation and hurricanes, is not convincingly narrowed down.

This workshop aims to provide an interactive platform to present and discuss ongoing work and opTropical Storm Nate 2017 10 06en questions about organised and self-organised phenomena in cloud fields. We especially invite thought-provoking contributions and new ideas.

The workshop aims to bring together the communities working on climate physics, statistical mechanics and meso-scale meteorology. The workshop will be organised around three core topics, mentioned below and in the scientific programme. 

A number of presentations will be on convection, but we are keen to also involve scientists working on related topics, such as soil-moisture and ocean (e.g. ocean mixed-layer) feedbacks.

We invite abstracts from three broadly-defined subject areas:

  1. Modelling and Parameterising Deep Convective Organisation
  2. RCE and Processes in Deep Convective Organisation
  3. Organisation in Shallow Convection

Format: All participants are encouraged to contribute by an interactive presentation. These will take place during three interactive sessions of two hours each, where participants can meet in virtual video chat rooms.
To promote an interactive workshop in virtual format, the invited speakers are encouraged to introduce the topic of each day and to lead subsequent panel discussions, where the presented contributions are summarised and placed into the context of ongoing research.
