Recently, IBM announced that it will release a new global weather forecast system that can forecast weather conditions 12 hours in advance, covering some areas where such detailed data are not available worldwide.
The new system, called IBM GRAF, the global high-resolution atmospheric forecasting system, will run on supercomputers to provide more detailed and high-quality forecasts. Previously, only the United States, Japan, and some Western European countries could obtain such accurate forecasts.
As extreme weather increases under the influence of climate change, more diverse renewable energy sources are put into use, and the demand for more accurate and timely weather forecasts is increasing.
The company said that the new forecasting system will provide data covering the whole world, including Asia, Africa, South America and some regions most vulnerable to climate change.
IBM GRAF is the world's first high-resolution, hourly update model covering global operations. In fact, a major limitation of global weather forecasts is the lack of data. IBM says the system has the ability to collect data from aircraft sensors and even smartphones, providing data on air temperature and pressure.
The current global weather model can cover 10 to 15 square kilometers and is updated every 6 to 12 hours. IBM's new system forecast can be reduced to 3 kilometers and updated every hour.
The relevant person in charge of IBM, Cameron Clayton, said that the new system introduced can be regarded as the real turning point in weather forecasting science.
To build this new modeling system, the IBM subsidiary and the National Center for Atmospheric Research (NCAR) jointly created IBM GRAF based on NCAR's next-generation open source global model, the cross-scale prediction model. It uses advanced technology to improve forecasting levels, and is able to predict the upcoming storm levels worldwide.
Using the IBM GRAF system to help decision-making also requires the support of technologies such as artificial intelligence. Incorporating these technologies will enable IBM GRAF Weather Forecast to better serve businesses and people worldwide.
