I can’t put it in quite the scientific language that Len uses but here is my take
Surface area of Earth 500 million sq.kms
Computer will use a grid of 1.5 x 1.5 kms = approx 2 sq.kms
Requires some 250 million input pieces of input data. How will this be achieved?
This massive number-crunching machine will only be as good as the input (nothing new in that concept)

Keeping up with ECMWF who are already planning to use the American's most powerful in the world computer at Oak Ridge.
But how about the physics? Can we parameterize at 1 km?Surface energy transfer is horribly complicated at that scale.

Yes Dave, I know about ECMWF's new ATOS computer.but I was referring to research they were going to do with the Oak Ridge supercomputer in USA.
Of course you are right about the data assimilation process.Hugely computationally expensive in the operational forecasts.I get a bit confused about the finances involved in improving weather forecasting.Presumably UKMO need £1.2 billion just because they operationally forecast.
Better let Boris and his mate Cummings know about this. After all Brexit means Brexit.
