The challenge: Our capability to simulate and observe the spatio-temporal organization of clouds and convection has strongly improved over the last decade. However, the fundamental understanding of what drives pattern formation in clouds and its effect on precipitation and on the strength of cloud feedback remain to be uncovered. 

The workshop: This scientific meeting aims to provide an interactive platform to present and discuss ongoing innovative work and open questions about organized and self-organized phenomena in clouds and convection. We especially invite thought-provoking contributions and novel ideas based on new observational field campaigns, e.g., EUREC4A, on high resolution, large domain simulations of tropical deep and shallow convection, extreme events including mesoscale convective systems (MCS), and on conceptual models and theoretical approaches. New insight into cloud microphysical and radiative cloud properties and their influence on organization are especially welcome.

On each day of the conference, we expect one or two themed sessions, opened by an invited keynote speaker and followed by contributed talks and posters.

The topics: The workshop will be organized around three broadly-defined themes:

  1. Conceptual models for cloud (self-) organization,
  2. Mesoscale organization of shallow and deep cumulus convection,
  3. Interactions between cloud organization and climate sensitivity.

The program: All participants are encouraged to contribute by either a poster or a talk (approximately 15 min + discussion). These contributions are broadly grouped into the three aforementioned topics. The updated program can be found here.

The venue: The meeting will be hosted in Utrecht at the Utrecht Public Library (website in Dutch). The library is an iconic building in the Amsterdam school style, located right in the heart of Utrecht on Neude 11, 3512 AE. It used to house the head post office and has been recently turned into a library and meeting space. Please note that Covid-19 precautions will be implemented as appropriate at the time of the meeting and in line with Dutch regulations and potential travel restrictions. Please visit this website for updated official guidelines.

The workshop dinner: A group dinner will be held on Wednesday evening at restaurant Stadsjochies, where we will enjoy a vegetarian dinner that includes greens grown at the restaurant. We have organised a boat trip to bring us from the Neude library to the dinner venue. We will also get a tour of the gardens while sampling the chef’s specialty mixed-drink - we look forward to a wholesome evening all together!
