pressure is a physical unit that measures what we may call the density of force i.e. trhe amount of force exerted on a certain area , the atmosphiric pressure is the force exerted by the air mass on a certain area , clearly more air means more mass , thus , when we go down the air above us increases , and when we go down the amount of air decreases.
The lower you are, the more air pressure you have weighing you down. The higher you go reduces that pressure.
The higher up you are, the less air pressure. The air thins out the higher you go, thus leaving less air in the atmosphere to push you down.
Barometric pressure (also known as atmospheric pressure) is the force exerted by the atmosphere at a given point. It is known as the "weight of the air". A barometer measures barometric pressure. Measurement of barometric pressure can be expressed in millibars(mb) or in inches or millimeters of mercury (Hg). Normal pressure at sea level is 1013.3 millibars or 29.92 inches of mercury. Fluctuations in barometric pressure are usually a sign of weather conditions. A rise in pressure usually means improving weather while falling pressure may reflect impending inclement weather. Barometric pressures will also vary with altitude and moisture.Barometric pressure in rio is 29.78 in hg and still rising
Barometric pressure goes down in a tornado.
The higher you go, the lesser the air pressure becomes. This can be logically understood. Atmospheric air pressure is caused by the weight of the air above it. At greater heights, the amount of air above you is less, so there is less weight pressing on the air you are in. This is the reason why the atmospheric pressure is higher at the sea-levels and lower at mountains and places of high altitudes.
A barometric pressure of zero is a vacuum.
no
Because pressure decreases as you go up in altitude and increases when you go down in altitude. Hope this helped!
Decrease
You cannot make that generalisation. Barometric pressure depends on altitude and on the current weather conditions.
A barometric pressure sensor is a type of sensor located within an engine system. It helps retain proper fuel mixtures at different altitude using barometric pressure measurements.
Radar altimeter gets altitude information by bouncing a radio wave off the surface of the Earth and determines the aircrafts altitude by measuring the length of time it takes for the signal to return. Barometric altimeters get altitude information by measuring the barometric air pressure outside the aircraft. Barometric pressure decreases as altitude increases. Radar altimeters will give altitude above ground level while barometric altimeters give altitude above sea level.
It would be the barometric pressure of the atmosphere which depends on the altitude of the person in question.

How does liquid pressure vary with depth
It's an airspeed indicator that compensates for outside temperature and barometric pressure at altitude.
The barometric pressure is what pilots use to gauge their altitude, however, all pilots above flight level 180 use 29.92. Barometric pressure is related to temperature changes, especially in higher altitude and mountainous areas.
At the altitude of 8,000 ft (2,438 m) the pressure is 1,572 pounds per square foot or 75 kilopascals.
