NOAA Goes Live With New Forecasting Supercomputers 53
dcblogs writes "The National Oceanic and Atmospheric Administration (NOAA) Thursday switched on two new supercomputers that are expected to improve weather forecasting. The supercomputers are each 213 teraflops systems, running a Linux operating system on Intel processors. The U.S. is paying about $20 million a year to operate the leased systems. The NWS has a new hurricane model, Hurricane Weather Research and Forecasting (HWRF), which is 15% more accurate in day five of a forecast both for forecast track and intensity. That model is now operational and running on the new systems. In nine month, NWS expects to improve the resolution of the system from 27 kilometers to 13 kilometers. The European system, credited with doing a better job at predicting Sandy's path, is at 16 kilometers resolution. In June, the European forecasting agency said it had a deal to buy Cray systems capable of petascale performance."

In the US anyway, TV weather persons don't do their own forecasts - they rely on their local National Weather Service reports. And those are based on actual meteorologists looking at what the US's GFS says, as well as the European ECMWF, and combining it with their own experience regarding what the models tend to get right/wrong locally.
UW's professor Cliff Mass has written, many times, about the problems with US weather prediction [blogspot.com]. The computers they rely on are old and less powerful than the European ones - plus it's exacerbated by the US NWS having a broader mandate, so the computers they do have are used to run several other types of simulations in addition to the standard weather models.
This purchase is definitely good news.
