The main types of variation of atmospheric pressure in physics are diurnal variation, which is the daily variation of pressure due to heating and cooling cycles; seasonal variation, caused by changes in temperature due to the tilt of the Earth's axis; and weather-related variations, such as those due to the passage of high or low-pressure systems.
A barometer is a scientific instrument used to measure atmospheric pressure. It helps in determining weather patterns as changes in atmospheric pressure can indicate approaching weather systems. There are two main types of barometers: mercury barometers and aneroid barometers.
The two main types of barometers are mercury barometers, which use a column of mercury to measure air pressure, and aneroid barometers, which use a small metal box that expands or contracts with changes in pressure to indicate atmospheric pressure.
Mercury and aneroid barometers.
In the field of physics, it is known that there are only two types of charge, positive and negative, based on experimental observations and mathematical theories.
A barometer typically consists of a glass tube filled with mercury or a liquid metal, sealed at one end and open at the other. The open end is placed in a container of mercury, allowing atmospheric pressure to push the mercury up the tube. The height of the mercury column is a measure of the atmospheric pressure.

Barometers measure atmospheric pressure using two main types: mercury and aneroid. A mercury barometer consists of a glass tube filled with mercury, where the height of the mercury column changes in response to atmospheric pressure; higher pressure pushes the mercury up the tube. An aneroid barometer, on the other hand, uses a sealed metal chamber that expands or contracts with pressure changes, moving a needle on a dial to indicate the current atmospheric pressure. Both types effectively provide a measurement of pressure, though they operate on different principles.
A compound pressure gauge measures both positive and negative pressure in a system. Positive pressure is the pressure above atmospheric pressure, while negative pressure is the pressure below atmospheric pressure. This type of gauge is commonly used in applications where both types of pressure need to be monitored, such as in HVAC systems or industrial processes.

Mathematical Variations are mainly of two types which are: -Direct Variation -Indirect Variation
A compound pressure gauge measures both positive and negative pressures relative to atmospheric pressure. It typically consists of two pressure sensors, one for measuring positive pressure (above atmospheric pressure) and one for measuring negative pressure (below atmospheric pressure). This type of gauge is commonly used in applications where both types of pressure need to be monitored, such as in HVAC systems or industrial processes.

Atmospheric pressure is measured by a barometer. There are several types. The one most likely to be found in a home is an anaeroid barometer.
