Barometer barometric pressure.

As temperature increases, pressure decreases. Conversely, as temperature decreases, pressure increases. As air warms, it rises in the atmosphere, resulting in lower barometric pressure. Cool air, on the other hand, sinks towards the Earth's surface, increasing the air pressure in that area. In general, areas of low pressure have a higher …Barometers measure atmospheric pressure, so you can get a general sense of what's going to happen by whether a barometer rises or falls. If the barometer goes up, then that means the weather is going to be fair. If it goes down, then it's probably going to rain, snow, or indicate some other type of inclement weather.A barometer is a simple instrument for measuring atmospheric pressure.

An aneroid barometer is a device used for measuring atmospheric pressure without the use of fluids. It typically consists of a sealed, flexible metal box known as an aneroid cell. This cell is designed to expand and contract with changes in atmospheric pressure. The aneroid cell is made from an alloy that is sensitive to pressure changes. Barometric pressure measures the weight of the air in the atmosphere pressing down against us. On average, the atmosphere exerts 14.7 pounds per square inch (psi) on the Earth’s surface. That pressure is called atmospheric pressure, or air pressure. It is the force exerted on a surface by the air above it as gravity pulls it to Earth. Atmospheric pressure is commonly measured with a barometer.
