It doesn't really come from anywhere. High pressure can form anywhere when air from aloft converges aloft and then is pushed downwards, compressed, and warmed. The air then divereges at ground level. Usually the air that has been compressed and warmed doesn't have any clouds because in the process of being warmed, clouds dissipate from the compressional warming.
Hope this helped!
Hkgh pressure and low pressure come toghether.
The well water pressure drops when water is being used faster than it can be replenished. Once the water level in the well has a chance to recover, the pressure will come back.

Hydrostatic and pumping
It is usually through being open to the pressure, allowing the internal pressure of the creature to match the exterior pressure.
The pressure from the pump is greater than the pressure within the tyre
No atmospheric pressure
Simply by following the manufacturers instructions that come with the various "pressure" tanks and ASME codes
The oil pressure is low or the sensor has failed.
well....because you lost air pressure
Air pressure does not come into play with most model rockets.
Pressure can be measured with a barometer, or a manometer.
