HD(CP)² - High Definitions Clouds and Precipiation for Advancing Climate Prediction

HD(CP)² is a BMBF funded German-wide research initiative to improve our understanding of cloud and precipitation processes and their implications for climate prediction.

The first funding period of HD(CP)² focused on the the optimization of the ICON (Icosahedral non-hydrostatic general circulation) model for Large-Eddy simulation (ICON-LES) with very high-resolution (horizontal spacing of 100 m) and on the improvement of ground, in situ and satellite based observations of cloud and precipitation events. The second phase, which started in April 2016, has a somewhat different structure. The project is no longer organized around the development of tools and infrastructure, but rather on different scientific questions related to cloud formation.

A United Research Effort

HD(CP)² brings together more than 100 scientists from 19 different institutes all over Germany. Altogether there are 46 PhD student and Postdoc positions associated with the project, making HD(CP)² a vivid example for the scientific leadership of young researchers. In its second funding period the project's core elements are science teams consisting of people from many different institutes in order to answer these striking meteorological questions:

  • How do clouds respond to pertubations in their aerosol environment?
  • What are controlling factors for boundary layer clouds?
  • What are controlling factors for anvil cloud development?
  • To what extent does land-surface heterogeneity control clouds and precipitation?
  • To what extent is convective organization important for climate?
  • How do clouds and convection influence the development of the storm tracks?
