Unreliable weather forecasts could become a thing of the past. 

Earth Sciences NZ has unveiled a new supercomputer called Cascade, which uses AI to predict the weather patterns. 

It can now make a five-day forecast as reliable as a two-day one. 

Chris Brandolino, Principal Scientist at NIWA, told Mike Hosking this supercomputer is about three times more powerful than its predecessor, with computing speeds of 2.4 petaflops. 

He says they’ll be able to expand the area they monitor, and then over the next year or so they’ll be looking to grow longer range predictions from 5-days to 10-days.
