AG01

Agulhas Nest at 1/10°

The focus of AG01 is on the ocean circulation around and near the southern tip of South Africa, especially the Agulhas system and its sources and extensions. To resolve mesoscale processes in this region adequately, a 1/10° AGRIF nest is embedded in a global ocean model at 1/2° (ORCA05). The successor configuration, which covers a larger region, is INALT01.

Simulations

The series of simulations with this configuration were completed in 2011. 

  • Climatological control run
  • Hindcast reference experiment (1958-2004)

HPC: 

Simulations and numerical experiments with this configuration are mostly done using high performance computing facilities at HLRS.
