When air pressure changes, it can affect the weather by causing winds to move from high pressure areas to low pressure areas, leading to changes in temperature and moisture. Changes in air pressure can also affect our ears, such as feeling the pressure difference when flying in an airplane or diving underwater.
During a tornado, changes in air pressure can cause your ears to "pop." This happens as your Eustachian tubes try to equalize the pressure inside your ears with the changing external pressure.
Air pressure changes mainly due to changes in elevation and changes in weather patterns such as the movement of high and low-pressure systems. As elevation increases, air pressure decreases because there is less air above exerting pressure. Changes in weather patterns can lead to alterations in air temperature and density, affecting air pressure.
The air pressure is rising.
Barometers measure air pressure.
Pressure changes in the atmosphere are primarily caused by the movement of air masses. When warm air rises and cooler air sinks, it creates areas of high and low pressure. Other factors like altitude, temperature changes, and weather systems can also influence atmospheric pressure variations.

When air pressure increases, the metal aneroid capsule in the barometer contracts, causing the needle to move towards high pressure. Conversely, when air pressure decreases, the metal capsule expands, causing the needle to move towards low pressure. This movement of the needle indicates changes in atmospheric pressure.

The changes are caused by the weight of air above it.
The air pressure drops sharply in a tornado
The air pressure is rising.
When air pressure increases, the aneroid barometer contracts, causing the needle to move clockwise or indicate a higher pressure reading. Conversely, when air pressure decreases, the aneroid barometer expands, causing the needle to move counterclockwise or indicate a lower pressure reading.
Barometer is the instrument that measures air pressure
The air pressure is high when the air is cold, and it's sinking.
air pressure decreases
changes in air pressure cause wind, but the sun is the major factor in changes to air pressure.
