What does the weather forecast of 100 degree mean?

According to the personal database, the weather forecast of 100 degrees means that the relative humidity reaches 100%, not the temperature. When the relative humidity reaches 100%, it shows that the water in the air tends to be saturated, and it is easy to condense into water drops when encountering smooth walls or glass, which is the most common phenomenon in rainy season.

Weather forecast, also known as meteorological forecast (measurement), refers to the use of 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). ).
