US pressure map is presented with information collected from the weather satellites and ground stations. What exactly is the pressure we are measuring and talking about? Gravity does its work by pulling these gases to the earth and making pressure on the atmosphere. While measuring the pressure, two things are kept in mind. The first is the weight of the atmosphere of that location, and the other one is the temperature of the location. In a place like a valley, where the altitude is low, the pressure will be higher because of all the air pressure presented in the area. This suggests that you will experience lower atmospheric pressure at high altitudes and higher atmospheric pressure at lower altitudes. An increased temperature can also lead to higher atmospheric pressure. When the air is warm, the molecules present in the air move faster causing higher atmospheric pressure. But when the air is low, the cold, the movement of molecules is much slower so the air pressure is considerably low.
