The main functions of typhoon warning are as follows:

1. Early warning residents and relevant departments: Typhoon warning can inform residents and relevant departments in the affected areas in advance to let them know that a typhoon is coming, so as to make preventive measures and preparations.

2. Ensure personal safety: The release of early warning can let people know the situation and power of typhoon as soon as possible, and remind people to take necessary safety measures, such as evacuating dangerous areas, looking for safe places and ensuring personal safety.

3. Provide meteorological information support: Early warning information includes not only the path, intensity and expected landing time of typhoon, but also meteorological parameters such as wind speed and rainfall, which can provide important information support for meteorological departments to monitor and forecast typhoons and further improve the accuracy and timeliness of disaster early warning.
