Low-pressure area - Wikipedia

A low-pressure area, low area or low is a region on the topographic map where the air pressure is lower than that of surrounding locations. Low-pressure systems form under areas of wind divergence that occur in the upper levels of the atmosphere.The formation process of a low-pressure area is known as cyclogenesis.Within the field of meteorology, atmospheric divergence aloft occurs in two areas.
