Why is the weather forecast more and more inaccurate now? Seek a scientific official explanation.

Now the weather forecast is getting more and more accurate. Why do we feel uncertain? The reason is that we are now relying more and more on weather forecast and paying more and more attention to it.

The weather forecast is only the analysis and prediction of the trend of the weather cloud picture, which can only predict the general situation, and it is normal not to predict every small point. For example, there is a rainstorm in Tongzhou, Beijing today. It cannot be said that the whole Tongzhou area is a rainstorm. Under the influence of other complicated factors, there must be places where it doesn't rain or it's not a rainstorm, don't you think?
