There is no epidemic area, and the concert is not limited. How to see the pressure of several days in the weather forecast?

Take a standard atmospheric pressure (i.e. 10 13 hectopascals) as the standard. Above this number, the air pressure is high, the weather is generally sunny, the ground diverges, and downward flow prevails. Below this number, the atmospheric pressure is lower and the weather is the opposite. Air pressure, that is, atmospheric pressure. Because of the air pressure, it depends on the empty density. Air density is related to temperature. The atmospheric pressure level in a place is an important meteorological data. Air pressure determines airflow, which is what people call wind. The greater the pressure difference, the faster the air flow.
