NOAA Goes Live With New Forecasting Supercomputers 53 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."

    I suspect if they removed the computers and installed windows in the offices of our local TV meteorologists we would get better short term forecasts. I've also decided that any precipitation forecast more than about 3-4 days out that doesn't involve a system as large as a hurricane is just a wild-ass guess*. Heck, even real time they're often wrong, the local guys are fond of reporting sunny all day while I'm actually looking outside at it raining.

    *Well, unless you're in SoCal Mar-Dec, in which case "Sunny" is always the statistically correct answer, or Orlando/Daytona, where "It will rain at 3:45pm for 5 minutes" is always the statistically correct answer.

    Please use American measurements, like rods and furlongs for distance.
