It's raining hard.
It judges the weather according to the changes of some atmospheric parameters such as air pressure and water content.
That is to say, according to the interaction of some atmospheric parameters in a certain range and the change law of some parameters in the past, the future change trend of some parameters at this point is calculated, so as to judge the weather situation at this point
But this calculation is not accurate enough, because there are many factors that affect the weather, and it is impossible to consider them all. There are still many uncertain factors, some factors that have not been seen or referenced, and some sudden small probability events.
At some points that don't need accurate calculation, considering the computing power of the computer, it is impossible to calculate them all.
Small changes in the parameters of the weather forecast model will affect the calculation accuracy of future trends. The accuracy of the computer here will also affect the calculation accuracy.
Therefore, the weather forecast is a general forecast and will not be very accurate. Theoretically, it can be accurate to the second, but some factors are not so accurate.
