Why is the weather forecast on the mobile phone inaccurate?

It must be said that the function of weather forecast now provides a lot of convenience for our life. Personally, I believe everyone will pay more attention to the weather when arranging their itinerary. But sometimes the weather forecast is not very accurate, which leads to missing the opportunity to go out or being trapped outdoors and causing trouble. Why is the weather forecast on the mobile phone inaccurate?

The forecast will be different.

In fact, not only the weather forecast on the mobile phone will be inaccurate, but also the weather forecast on other media. The data source is the Meteorological Bureau. However, people may be more superstitious about the weather forecast on TV and radio because it seems to be more authoritative, but it is not. The predictions made with the same data are naturally the same.

The weather forecast is just a weather forecast. According to the current weather state, cloud, wind, temperature and other factors, it is more accurate to predict the weather state in the future. However, we can't control the change of the weather. Maybe there will be other unexpected changes after the weather forecast. "You never know" is not empty talk. Therefore, the weather forecast is only a high probability forecast, not an inevitable event.

The longer the time span, the more difficult it is to predict.

At present, the weather forecast on mobile phones basically has time-interval weather forecast, which can be accurate to the hour level. Generally speaking, the hourly weather is accurate, because there are few unpredictable changes in recent times, so the forecast is relatively more accurate. However, some weather forecasts for three or four days, one week and fifteen days actually only report a general weather trend, and it may rain, but the number of rainy days is not accurate, and it may heat up, but it is impossible to say how much it will rise. The longer the time, the greater the possibility of change, so the short-term weather forecast is more accurate than the long-term forecast.
