#3This is fantastic - would be really exciting to see this level of resolution making its way to global operational weather forecasts (currently at ~10km).

#41.25 ~ 1.3: Round half to odd prefers preserving the existing scale of tie numbers avoiding out-of-range results when possible for numeral systems of even radix.

#5I have only one question. Does this mean that we are getting closer to a cloud-hosted ultimate map for games like Call of Duty and Ace Combat?
I want to dogfight over Ohio, land at Offutt to play Warzone in Omaha, then take a MRAP and drive to NY.

#7>throughput of 2.5 simulated days per day
Will need to be at least 10x faster to be operationally useful.

It's far too expensive with dubious impacts on forecast quality. Adaptive mesh approaches are far more suitable for high res global weather modeling... Why simulate the area under boring, dynamically unimportant areas?

#10This is for short term weather prediction or long term climate modelling? The 2.5 simulated days per day points into the short term direction.
