Decreasing pressure (below 1000 millibars) corresponds with cloudy, rainy weather. Highest barometric pressure (record): 1084 millibars ...Barometric pressure is a measurement of the air pressure in Earth's atmosphere. For this reason, it is also known as atmospheric pressure. The pressure is created by fluid gas molecules in the air, and it extends in all directions. Notably, it exists as downward pressure exerted on the ground on Earth, which makes it relatively easy to measure. Atmospheric pressure can be measured with a mercury barometer (hence the commonly used synonym barometric pressure), which indicates the height of a column of mercury that exactly balances the weight of the column of atmosphere over the barometer. 6.
