How does Apple's mobile phone send weather forecast to others?

It has a sharing function, which will automatically generate pictures, including weather, air quality, temperature and other information, which can be turned with one button.

Weather forecast (measurement) or meteorological forecast (measurement) is to use modern science and technology to predict the state of the earth's atmosphere in a certain place in the future. Since prehistoric times, human beings have begun to predict the weather and arrange their work and life accordingly (such as agricultural production and military operations). Today's weather forecast is mainly based on the collection of a large number of data (temperature, humidity, wind direction and speed, air pressure, etc.). ), and then use the understanding of atmospheric processes (meteorology) to determine future air changes. Because of the chaos of the atmospheric process and the fact that science has not fully understood the atmospheric process today, there will always be some errors in the weather forecast.
