Note: due to the coronavirus epidemic, we are temporarily suspending meeting registration and will re-open as soon as possible, with an updated registration deadline.

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, along with some examples of the type of questions we would like to address. 

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. Detecting and understanding regimes of organisation,

  2. Organisation as a tool for model evaluation,

  3. Introducing organisation into climate models.

All participants are encouraged to contribute by a presentation. These will either be as talks (~ 20 minutes including questions) or posters.
