The weather forecast data of each platform is different. What is the reason?

Because they are all updated once, some are updated every few minutes, and some are updated at different times every day, so the weather forecast results may be different from family to family, so we only need to make a reference. The weather forecast is a content that every one of us basically watches every day. Because we need to predict our travel situation and the thickness of clothes the next day according to the weather forecast, it is particularly important. Because it is related to everyone's life, the accuracy of the weather forecast is also very necessary and important. ? But many people say that the weather forecast predicts that every family is different, and the situation of pre-explosion in every family is different. Actually, we don't have to dwell on this problem. We just need to know a general idea. After all, the weather forecast is a reference value, and the weather will change at any time, so sometimes when you see this situation, we just need to make a reference. ? In addition, different test sites will lead to different results. Moreover, there are currently more than 2,600 meteorological stations in China's meteorological system, including 2,300 meteorological stations and 3 10 meteorological stations all over the country. Therefore, it is normal for them to make some mistakes. We just need to make a reference value. Generally speaking, their weather forecast will not change in a particularly large range. ? Moreover, the weather forecast is calculated with big data, and the specific data is not the same as the analysis method, and the analyzed data structure is also different, so if the results are different, I don't need to delve into it particularly, as long as their measurement results are similar, we just need to make a reference.
