This is for short term weather prediction or long term climate modelling? The 2.5 simulated days per day points into the short term direction.

I wouldn't think that a temporal resolution measured in days is needed or all that helpful for climate modeling.

I'm not sure the added precision is helpful if it's just 2.5 days ahead. An extra week of accurate forecasts is a bit pointless if it takes 8 days.

  Simulating 8 days would take 8/2.5 = 3.2 days.

  When you’re trying to assess imminent danger from an approaching tropical cyclone, days and hours count. A lot.

As mentioned in the article, the system is based on the ICON Earth System model[1], which has the following description: The Earth system model provides a numerical laboratory for research on the climate dynamics on time scales of a season to millennia. Necessarily most processes are parameterized to allow the computationally efficient integration over long periods. It's also mentioned it will contribute to DestinE[2]: Destination Earth (DestinE) aims to develop – on a global scale - a highly accurate digital model of the Earth to monitor and predict the interaction between natural phenomena and human activities. [...] The initial focus will be on the effects of climate change and extreme weather events, their socio-economic impact and possible adaptation and mitigation strategies.

  I am working on DestinE with workflow managers and posted my first entry in Who's Hiring some days ago. Lots of work and interesting challenges if anyone is interested in earth system models, NWP, workflows, HPC, GPU's, data formats, etc. Not only on my company, the BSC in Spain, but also in other countries/companies as well.
