Official rumor: this year is the coldest year in the next 10 year. How accurate is the weather forecast?

Everyone must love and hate the weather forecast, because sometimes the weather forecast is particularly accurate, so everyone can prepare and take precautions in time, but sometimes the information in the weather forecast is not completely accurate, and the official has publicly rumored that this year is not the coolest year in the next decade, and according to this information, the official has not put forward any data, so this is a rumor. So how accurate is the weather forecast? In fact, the accuracy of weather forecast depends entirely on weather changes and various data. Under normal circumstances, according to the level of modern science and technology and various data analysis, the accuracy of weather forecast can reach more than 80%. If you carefully look at the weather forecast in recent days, the accuracy rate may reach more than 90%. If you directly know the weather after a week, the normal accuracy rate can reach about 60%. Therefore, according to these official data, and as we all know, the accuracy of weather forecast is generally high, but as far as this percentage data is concerned, as long as it is not completely close to 100%, there is a possibility of some change, and the weather change is beyond people's control, so in any case, the weather may change extremely, so the accuracy of weather forecast will definitely not reach 65438. Because it is very difficult to achieve more accurate prediction, it may be necessary to increase the value of any data exponentially, so that the accuracy can be improved again. However, such data is already huge, which requires not only sophisticated technology, but also professional talents. Therefore, the accuracy of the weather forecast is very accurate for the weather within 24 hours or 48 hours, and it can completely depend on the weather. Although the weather sometimes changes, this situation is already a group of weather. Even a completely accurate weather forecast can't predict this kind of weather, because sometimes it needs experience to judge, so the accuracy of weather forecast can reach about 90% in a short time.
