So, meteorologists （气象学家） are working hard to predict them. AI is playing an important role in this work. ②For years, meteorologists have used computers to make models of storms. They use information from planes and satellites （人造卫星）.It takes those models hours to create predictions. But AI models use lots of data from past 刷速度 返回目录 13 storms to find patterns （模式）.They can find rules that most humans can’t. And they can do this very quickly. This year, AI models made accurate （精确的） predictions in just seconds about storms, sometimes even how many days before they happened. ③One AI program called GraphCast correctly predicted that Hurricane Beryl would hit Texas on 8th July, while a traditional model predicted it would hit Mexico. GraphCast was right, and the team behind it won an engineering prize. ④In September, another AI program called AIFS predicted the path of Hurricane Francine as it hit Louisiana. Because it was so accurate, Matt Lanza, a 刷速度 返回目录 meteorologist in Houston, Texas, told people in Texas that the storm wouldn’t be a problem for them.“It was really amazing,” Lanza said. ⑤Even though AI is helpful and has made significant. .success, it’s still not good enough. Lanza said that AI models have trouble predicting how strong a storm will be and how much rain will fall.
