HD(CP)² involved in Nature Publication

The HD(CP)² and HErZ members Daniel Klocke, Matthias Brueck, Cathy Hohenegger and Bjorn Stevens recently published an article on new storm-resolving simulations. These show how resolved convection, and its associate circulations, interact and form the larger scale circulations within the Atlantic intertropical convergence zone (ITCZ).

One of the most prominent features emerging from those simulations are the doldrums - a largely forgotten region of calm and variable winds in the deep tropics which extends across vast parts of the tropical Atlantic ocean.
The simulations, given their grid spacing (2.4 km), simulation domain (3000x9000 km) and integration period (2 months) open exciting new opportunities as they are able to both explicitly capture small-scale features of the atmospheric flow, like the gust wind of a convective storm, and the whole atmospheric circulation over the tropical Atlantic on timescales interesting for climate studies. Basis for these simulations was laid with the tropical Atlantic (Opens internal link in current windowTA) simulations done in HD(CP)².
