Why is the weather forecast in Kunming not accurate at all? Why didn't you tell me the truth?

The accuracy of weather forecast is influenced by many factors, including the uncertainty of forecast model, the complexity and variability of meteorological phenomena, etc. Therefore, the weather forecast can only provide a rough forecast, rather than 100% accurate results.

In addition, personal perception and observation may be different from weather forecast, because personal observation is influenced by many factors, such as observation location, weather conditions and personal feelings. Therefore, if personal observation is inconsistent with the weather forecast, it does not necessarily mean that the weather forecast is inaccurate.

In a word, the accuracy of weather forecast is a complex problem, which is influenced by many factors. Although the weather forecast may have some errors, it is still one of the main tools for us to understand the weather.
