Barometric Pressure

What is barometric pressuer? Have you ever wondered as you read the news what exactly a kilopascel was and how it effected barometric pressure... in fact what the heck barometric pressure actually is? I know I have... so here's the anser:

Barometric pressure, otherwise known as atmospheric pressure is the pressure exerted by the weight of the column of air above a given point, expressed in kilopascals. Generally speaking, when the barometric pressure is high, the air is sinking, usually resulting in fair weather. When the barometric pressure is low or falling, air is rising, usually resulting in cloudy skies and precipitation.
