Logically, what does a continu- ally rising air pressure indicate ?

Atmospheric pressure is the weight of a column of air exerted on a unit area [1]. A continually rising barometric pressure indicates the development or approach of a high-pressure system, also known as an anticyclone. In high-pressure systems, air subsides from above and diverges at the surface, which inhibits the rising motion necessary for cloud formation and precipitation [3]. Consequently, rising pressure is a reliable indicator of clearing skies and the advent of fine, settled, and stable weather conditions. Conversely, falling pressure is associated with converging air and rising motion, which leads to unstable weather, clouds, and cyclonic conditions [2]. Therefore, a steady increase in pressure signifies improving weather and the departure of unsettled conditions.
