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. The Working Group on Numerical Experimentation (WGNE) has initiated the Grey Zone Project as a response to the need to systematically explore the behaviour of the models operating in the “Grey Zone.” 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.
