Barometric pressure is another name for atmospheric pressure, named after the instrument barometer used to measure it. Barometric pressure is caused by the Earth's gravity acting on the atmosphere. We can look at barometric pressure as the pressure acting at any point on Earth due to the "weight" of the air above this point.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 …An essential skill in the realm of weather forecasting, interpreting barometric pressure readings is the key to unlocking the upcoming weather conditions. A steady barometer hints at stable weather, while a rising barometer alludes to improving conditions. Conversely, a falling barometer serves as an omen of potentially changing or adverse ...Both barometers are exposed to atmospheric pressure. The barometer with mercury shows mercury levels of 2.49 feet. The barometer with water has a much greater level of 33.9 feet. If the liquid is water, normal atmospheric pressure will support a column of water over 10 meters high, which is rather inconvenient for making (and reading) a barometer.The first barometers used a J-shaped glass tube with mercury in; higher air pressure pushes the mercury column higher up the long tube, so its height shows us the air pressure. These barometers can still be seen in stately homes, but they are very unwieldy, and since 2007 it is only possible to purchase a mercury barometer as an antique due to ...
