Convection resolving simulations with ICON

Convection resolving ICON simulation

The animation shows convection resolving ICON simulations over the tropical Atlantic accompanying the NARVAL campaigns (by Daniel Klocke, DWD and Matthias Brueck, MPI-M). Emergent phenomena are featured in unprecedented detail, ranging from cold-pools of small cumuli, interacting squall lines of deep convection to hurricanes evolving from breaking easterly waves. Over 40 days are already simulated within the period of NARVAL-I (Dec 2013) and NARVAL-II (Aug 2016). The model resolution is 2.5 km with a nested domain of 1.2 km over the western part of the domain. These results are further used as input to large-eddy simulations with ICON within the HD(CP)2 project.


Parallel Performance of ICON


The graph shows the parallel performance of the ICON software using ECHAM physics on a 5km-resolution aqua-planet experiment. Good strong scalability is observed on the partition compute2 hosted at DKRZ. Find out more about ICON scalability and benchmarking here.


Coupled Systems: Sea-Ice Extent


Check out an animation of a simulation of the arctic sea-ice extent over the years 1994-2003. The simulation was carried out using the CERFACS-HR model.

Coupled Systems: Atmosphere-Ocean Circulation Model

Check out a single-member atmosphere-ocean simulation of the north-Atlantic ocean region (temperature distribution over the years 1993-2000).


ESiWACE: WP4 (Exploitability) @SC16

ESiWACE participated in Supercomputing 2016 in Salt Lake City, Utah.

Find out more about modeling and simulation of tape libraries (WP4 of ESiWACE) here (poster, pdf).

Check out a short paper on middleware for earth system data here. This contribution was submitted and accepted as short paper at the International Workshop on Parallel Data Storage and Data Intensive Scalable Computing Systems, held in conjunction with SC16.
