High and Low, Fair and Foul. High barometric pressure is associated with calm weather, whereas low pressure usually brings stormy weather. As air cools, the molecules pack together, making it denser and thus increasing the pressure. This dense air presses down on the air beneath it, causing that air to grow warmer.
When the air pressure rises, it pushes the mercury higher. When the air pressure drops, so does the mercury level.. Atmospheric pressure can also be measured in millibars (mb), with a bar being roughly equivalent to one atmosphere of pressure (one atmosphere equals 1.01325 bars). One bar is equivalent to 29.6 in. Hg.A barometer reading of 30 inches (Hg) is considered normal.
