Standard Atmosphere is mainly used as a reference value for the average atmospheric pressure at sea level. It is often used to indicate the depth rating for a water resistant watch, but otherwise is rarely used as a unit for measuring pressure. 1 standard atmosphere is defined as being exactly...
At sea level, air pressure is about 14.7 pounds per square inch (1 kilogram per square centimeter), and the atmosphere is relatively dense. At 10,000 feet (3 km), the air pressure is 10 pounds per square inch (0.7 kg per square cm), which means molecules of gas that make up the ...
This seems to have a considerable effect on the distribution of the earth’s atmospheric pressure, and consequently on wind circulation. The sun is also variable over a long term: its heat output goes up and down in cycles, the latest trend being downward.这似乎对地球大气压力的分布有相当大的...

A program of pressure measurements with rockets over White Sands, New Mexico, and over the equator has given values for atmospheric pressure, density, and temperature from the ground up to 160 km above sea level. The data have been obtained from about a dozen rocket flights at White Sands, ...
Atmospheric Pressure: Atmospheric pressure is the force corresponding to the one-unit area applied by the weight of the Earth's atmosphere on the surface of the Earth. It is also sometimes referred to as air pressure or barometric ...
