Global High-Resolution Atmospheric Forecasting model offers high resolution weather forecasts globally with a detail for areas as small as 2 miles wide, compared with 6 to 9 miles. Its new supercomputer, DYEUS, built just to run the model, will issue 12 trillion pieces of weather data every day and process forecasts every hour, while many global weather models update only every six to 12 hours. The weather forecasting system will provide data to cover the world, including Asia, Africa, and South America, some of the region most vulnerable to the effects of climate change. The current global weather models cover 10-15 kilometres squared (km sq) and are updated every 6 to 12 hours. IBM’s new weather forecasting system will forecast down to 3 km sq and update hourly. Access to high-resolution weather data will help plan better for planting or harvesting.
