The point was that weather, unlike a sandheap, is a chaotic hydrodynamic system with turbulent flows, that means it's computationally intractable to do exactly, which is why weather forecasts are only good for a few days anyway.
The example you gave does not really explain anything.
- londons_explore 3y agoThe sandheap is chaotic too - just one sand grain tumbling can be enough to start a landslip. But the end result tends not to depend on the minute details - if sand grain A didn't cause the landslip, then a few seconds later sand grain B would have.
