Researchers at the RIKEN Advanced Institute for Computational Science in Japan have used the K supercomputer to show incorporating satellite data at frequent intervals into weather prediction models can improve rainfall predictions and enable more precise predictions of typhoon development.
They used data from Himawari-8, a satellite that can scan the entire area it covers every 10 minutes in both visible and infrared light, at a resolution of up to 500 meters.
When studying the behavior of Typhoon Soudelor, a category 5 storm that struck the Pacific region in late July and early August 2015, the researchers found their new simulation more accurately predicted the rapid development of the storm.
"It is gratifying to see that supercomputers, along with new satellite data, will allow us to create simulations that will be better at predicting sudden precipitation and other dangerous weather phenomena," says RIKEN's Takemasa Miyoshi.
