Workshop on understanding Convective Self-Organization


Cloud self-organization over the Western Pacific (NASA)

Cloud self-organization over the Western Pacific (image: NASA). Image acquired by MISR’s nadir camera on March 11, 2002. Image centered west of the Marshall Islands.

Please join this small and focused workshop on simple, idealized, models related to the self-organization of the convective cloud field. The aim is to have short presentations (roughly 30 min per speaker) and plenty of room for debate. We would like presentations to open up the discussion on new, meaning: only partially developed, ideas which can perhaps turn into joint projects as an outcome of the workshop.

The focus is on self-organization: from "within", from "the outside" and "from the boundary".

Basic Topics

  • Conceptual models (SOC, percolation etc) and their relation to the underlying physics,
  • Organisation and dynamics (vorticity, helicity, geometrical aspects),
  • Role of other processes (land-surface, microphysics and radiation): What does a model need to get right here? Do simple models work here as well (and how would we know? Is there observational evidence?)
