The Central Meteorological Observatory has a daily weather forecast for Huangyan Island. Now, how can I record the previous historical records of the Central Meteorological Observatory? Thank you.

The weather forecast is updated three times a day, and the website will not keep the historical weather forecast data, because the past weather forecast is meaningless to the public, but the meteorological department will have its own records to test the accuracy of the forecast and summarize the mistakes of the forecast as the basis for improving the accuracy of the forecast in the future. Therefore, the public can't keep the historical data of weather forecast.
