Why is the weather forecast in Gongzhuling inaccurate?

Sometimes the weather forecast is inaccurate for three reasons:

1. The weather forecast needs a lot of meteorological observation data to support it. However, some areas are limited by topography and there are few observation points, such as the ocean and the Qinghai-Tibet Plateau.

2. Congenital deficiency of observation data will affect the accuracy of weather forecast.

3. Inaccurate instruments and instruments that need to be calibrated will also affect the accuracy of the forecast.
