The accuracy of Kunming weather forecast 15 days is high.

The weather forecast for the next 15 days is not very accurate. Because of the chaos of the atmospheric process and the fact that science has not fully understood the atmospheric process today, there will always be some errors in the weather forecast. Any forecasting model can't completely and truly simulate the evolution of the atmosphere, it can only be approximate, so there must be errors. Moreover, the error will accumulate, and the longer the prediction time, the greater the error.

Weather forecast refers to the forecast of weather changes in a certain period in the future, including short-term, medium-term and long-term weather forecasts.
