U.S. Model Issues Reach Main-Stream Media

Meteorologists have been talking about the long-range model issues for several years now, and many viewers of local weather already know that their local forecaster depends on the European long-range model much of the time. The superior performance of the European ECMWF global model made news during Hurricane Sandy, and the public likely first heard about the issue then. Congress did, because due to public pressure (and embarrassment?) NOAA finally …

NOAA Makes Decision on New Global Weather Model. Controversy Likely.

NOAA has decided on the nuts and bolts of a new, next generation, weather model that will replace the present Global Forecast System (GFS model), and the choice is sure to spark some controversy. The choice boiled down to a system called MPAS vs FV3. Many meteorologists were rooting for MPAS, which was developed by NCAR, while NOAA was leaning toward the FV3 which was a project of the GFDL …

Major Advance For Weather Prediction In The U.S.

This is a guest Post from University of Washington Professor of Atmospheric Sciences Cliff Mass. It is a re-post from his popular blog here. This is important. Today, NOAA’s administrator Kathryn Sullivan announced that the National Weather Service will acquire two very powerful CRAY supercomputers to support U.S. numerical weather prediction.   A machine that will FINALLY allow the U.S. to do world-class forecasting.  (The press release is here). In a number …

Seriously Behind; U.S. Near the Bottom In Weather Forecast Computer Power (Guest post by Cliff Mass)

Besides the increasing gap in weather satellite technology, Europe and Japan are also well ahead in computer power available for numerical weather prediction models. Almost every U.S. forecast meteorologist this winter has relied on the global model from the European Center for Medium Range Weather Forecasting, (based in London) rather than the NOAA Global Forecast system. Short range forecasts are handled well by the NOAA high-resolution models centered over North America, but for forecasts beyond three days a global model is needed. …
