The U.S. will triple the weather computing capacity, but is it enough to surpass the European model?
about the models and why computing capabilities have historically given the Europeans a slight advantage. However, the United States government made a major announcement this week that may signal that its model is making a play for weather model front-runner.... [+]Is this enough to surpass the Europeans? I don’t know - maybe. To me, it really doesn’t matter whether the U.S. is leading the pack.
I should also mention that the United Kingdom weather modelers recently announced massive computing upgrades that rival European and U.S. efforts. At higher levels, administrators and meteorologists laugh at the notion that this is some type of competition. As president of the American Meteorological Society a few years back, I literally watched a high-level ECMWF official chuckle at dinner with me in England when I mentioned bickering about the models. Another point that goes overlooked is that the U.S. federal weather enterprise has to leverage its budget in many directions: new satellites, radars, forecast offices, and so forth.
ECMWF has a different paradigm and budget strategy so can sink resources into the biggest, fastest supercomputers. They also use a sophisticated technique for ingesting satellite and other datasets into their model. By the way, much of that satellite data is from U.S. and other international satellites so the success of the Euro model is not independent from other partnerships.days in advance.The U.S. has big computers too.
