Is the weather forecast of CCTV accurate or that of local stations accurate?

Because of hardware resources (such as meteorological satellites, meteorological comprehensive analysis systems, etc. ) The Central Meteorological Observatory called is richer and more accurate. The weather forecast of CCTV is macro (nationwide), so it is more abstract in a certain area.

In addition, the weather forecast of local stations is generally collected by themselves, so it is closer to the local reality. However, compared with the Central Meteorological Observatory, its macro-trend analysis and pre-judgment ability is still slightly insufficient.
