In a potentially historic marriage of supercomputing and big data, IBM goes live Thursday with a global weather model that it says can provide far more accurate forecasts for the entire world.
Called GRAF — Global High-Resolution Atmospheric Forecasting — the new model offers high resolution weather forecasts globally with a detail for areas as small as 2 miles wide, compared with 6 to 9 miles for weather models covering parts of the world outside such advanced regions as Europe, the U.S. and Japan.
