Have you ever observed that there is atmospheric pressure all around you? Also known as air pressure, it is the pressure exerted on us by the tiny air molecules or air particles. Despite their size, molecules of air have weight and occupy space. However, air molecules can be compressed and fitted in to a smaller space as there is plenty of empty space between the particles. Compressed air, or air fitted into a smaller space is called high pressure air or as being 'under high pressure.' In fact the air we are so used to is constantly applying pressure on us, but we don't actually feel it.
How are air pressure and weather connected?
