AI is like giving superpower to computers. It helps them to learn things and do tasks that people usually do. According to scientists, AI could be used to tell the weather more quickly and correctly than traditional methods.
The traditional way to tell the weather is by collecting data on what is happening in the air. The data may come from places like weather satellites, planes and so on. Then the data is sent to supercomputers for weather reports. Although supercomputers are powerful, it can take many hours to produce results.
AI models have been developed to quickly tell future weather. They can tell the weather by using two sets of data:the weather at present and the weather from six hours ago. AI models are very helpful. They can be used on ordinary computers like office computers, and it only takes a few minutes to get the results. However, the results may not include as much information as those produced by traditional models.
Will AI take the place of traditional models? Scientists say it probably wont, but it will be used together with them. Thats because AI still needs to learn from the data collected by traditional methods. But hopefully, AI will be able to deal with tasks that older methods find difficult, such as telling when and how much it will rain in the near future. This could give people enough time to solve the problems caused by bad weather.
