so long as attention was confined to daily mean values of pressure, I have now obtained results pointing to a hitherto unsuspected relation between the type of the diurnal variation of pressure and the general state of magnetic conditions, as regards disturbance and quiet, over the earth. As...
Atmospheric pressure is the pressure at any point in the Earth's atmosphere. In most circumstances atmospheric pressure is closely approximated by the hydrostatic pressure caused by the weight of air above the measurement point. Low pressure areas have less atmospheric mass above their location, ...
4. When the atmospheric pressure in the Artic is higher than the area outside the pole, the cold air spreads. 5. Methane is a flammable gas on Earth but liquid on Titan because of the moon's intense atmospheric pressure and cold. ...

Atmospheric pressure is simply the sum of those many forces. On average, the atmospheric pressure on Earth, at sea level, is 14.7 pounds per square inch. This means that there is a force of almost fifteen pounds pushing against every single square inch of your entire body. View Video ...
The pressure also presses the molecules in the lower atmosphere closer together. This means that the higher the air pressure, the greater the air density. For this reason, 50 percent of Earth's air exists below an altitude of 3 miles (5 km). Standing at sea level, the atmosphere exerts,...
Millibar, unit of air pressure in the metric system, commonly used in meteorology, equal to 100 pascals, 1,000 dynes per square cm (about 0.0145 pounds per square inch), or slightly less than one-thousandth of a standard
Atmospheric Pressure: Definition & Facts Books on meteorology often describe Earth's atmosphere as a huge ocean of air in which we all live. Diagrams depict our home planet as being surrounded by a great sea of atmosphere, a few hundred miles high, divided into several different layers. And ...
