Low-pressure area

Area with air pressures lower than adjacent areas

In meteorology, a low-pressure area (LPA), low area, or low is a region where the atmospheric pressure is lower than that of surrounding locations. It is the opposite of a high-pressure area. Low-pressure areas are commonly associated with inclement weather (such as cloudy, windy, with possible rain or storms), while high-pressure areas are associated with lighter winds and clear skies.
