Collaborative Workshop on "Scales and scaling cascades in geophysical systems" a full success

Our fourth annual workshop on "Scales and scaling cascades in geophysical systems" was held from April 4-6, 2018 at "Haus des Sports" in Hamburg, Germany.

Over 100 scientists from all over the world gathered in Hamburg for our annual workshop.The topic of the workshop was "Scales and scaling cascades in geophysical systems".

Complex processes involving cascades of scales pose ubiquitous challenges in natural science research. Often the smallest and largest scales are widely separated in such processes, as e.g. for the different dynamical regimes in atmosphere and ocean: gravity waves, small-scale turbulence and geostrophically balanced flow. Interactions between the smallest, largest, and intermediate scales connecting different dynamical regimes challenge our established theoretical or computational tools and the formulation of consistent models.
