After the weather forecast is made, the weather forecast is published to the society through various ways. At present, the approaches for transmitting weather forecast mainly include television, newspaper, internet, short message service, weather telephone, etc. It is a future trend to acquire weather forecast information through the internet. Weather stations around the world receive weather records from weather stations at any time each day.
