Why is the weather forecast on the Internet different from that broadcast by CCTV? All belong to the Central Meteorological Observatory. I hope the insiders can explain.

If the forecasts all over the country, from provinces to counties and townships, are reported by the Central Meteorological Observatory, it is estimated that they must have been exhausted, and different regions and different situations need to be revised by the local meteorological department. For example, if your home is in the county seat, the forecast result of your city is likely to be different from that of your county seat, which involves a regional fine forecast problem, but generally speaking, there will be no big difference, there will be no heavy rain in the city and no sunny day in the county seat. In fact, the National Bureau is responsible for the assessment of the national weather situation, and the forecast is made as follows.

The Central Meteorological Observatory basically does not make specific local forecasts, but they are responsible for guidance and analysis. The sources of online forecast information are different, and it is normal to have differences, but generally there will be no big deviation.
