WGNE/GASS Workshop: The Grey Zone Project


December 1-3, 2014
Max Planck Institute for Meteorology
Bundesstrasse 53
D-20146 Hamburg
Germany





As a result of the ever increasing computer resources, more and more numerical weather and climate models are operating in the so called "Grey Zone" at horizontal resolutions in the range of 1 to 10 km. As these resolutions exceed the depth of the atmosphere, they allow for numerically resolved vertical turnover behaviour, but clouds and convective transport are only partly resolved. As a response to the need to systematically explore the behaviour of the models operating in the "Grey Zone", the Working Group on Numerical Experimentation (WGNE) has initiated the Opens external link in current windowGrey Zone Project.

A WGNE/GASS workshop on the "Grey Zone Project" will be held at the Max Planck Institute for Meteorology, Hamburg, Germany on December 1-3, 2014.

The objectives of the workshop are to:

  • present and discuss the Model Intercomparison Study on the Cold Air Outbreak such as observed during the CONSTRAIN field campaign,
  • present and discuss novel ways of representation of physical processes (i.e. clouds, convection and turbulence) in the grey zone,
  • discuss any further coordinated future activities.


We kindly invite all the modellers that have participated in the intercomparison study, but also other scientists who have an interest in the topic of how representing physical processes such as clouds, turbulence and convection in models that operate in the grey zone with respect to these processes.
