Wuhan weather forecast accuracy 15 days

The accuracy of Wuhan weather forecast 15 days is not high.

All weather forecasts are similar, but they all have certain accuracy.

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.

The forecast of 8- 15 days is objectively revised, but it has not been subjectively revised by forecasters, so there is some uncertainty.
