Influence area for local forecasting over a particular place e.g.France

How many degrees of freedom are there?
![]() | There is more than 100 000 000 degrees of freedom. We need to forecast the system before real time occurs! |
How can we compute such an huge system?

First, split the domain into subdomains

Then, compute fields over each subpart of the flow

Communication between subparts make evolving flow in time
