In what year did the first TV weather forecast in China begin?

The earliest meteorological observatory in China was the Xujiahui Observatory in Shanghai, which was built in 1872. At that time, the weather forecast only contained vague and simple contents such as "the wind direction in the whole country is uncertain, the weather is changeable and it may rain". In July 198, they broadcast the first TV weather forecast in China on CCTV. Now the weather forecast you see has used high-tech means such as satellite and radar, not only short-term forecast for one or two days, but also long-term climate forecast across seasons and years, and real-time system forecast.
