Why is the weather forecast always inaccurate? What exactly is this card point?

Because the weather itself is uncontrollable, the uncertainty of the weather, the density of weather stations and the complexity of calculation are all reasons for the inaccurate weather forecast.

Ancient people had the habit of taking an umbrella when they went out, because sometimes it seemed that the weather was fine and there would be a downpour when they walked. In those days, it was quite extravagant to ask a doctor, so it was not particularly troublesome to take an umbrella with you. In modern times, it is more convenient. You only need to turn on the weather forecast to know the weather in the next few hours. Although the weather forecast is calculated by scientific means, there will inevitably be errors.

First, the uncertainty of the weather As the saying goes, when it rains, my mother wants to get married. No one can control these two things, and no one has the right to control them. The weather itself is a very casual thing. Sometimes one second it's sunny, and the next it's overcast and raining cats and dogs. Sometimes it is clear that large dark clouds are ready, but at this time a strong wind blows them away and the rain falls to other places. Even if the weather forecast system is accurate, it is not smart enough to detect emergencies at any time.

Second, the density of weather stations In order to prevent buildings from blocking and to facilitate the overall planning of the city, weather stations are generally built in relatively empty areas on the edge of the city, which determines that their coverage cannot be concentrated in every place, and it is inevitable that there will be omissions, and the detected data will be slightly biased, which will affect the final result. At the same time, advanced testing instruments will also affect the accuracy of data. Although people have been improving this technology, it is still insignificant for complex weather systems.

Third, the complexity of calculation. After the monitoring value is fed back, it should be input into the calculation system according to a certain formula. When operating with different parameters, different weather results will be produced, and these errors are allowed, so the broadcast weather forecast will be inaccurate.
