In meteorology, a low-pressure area, 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), [ 1 ] while high-pressure areas are ...
A low-pressure area is a region where the atmospheric pressure at sea level is below that of surrounding locations. Low-pressure systems form under areas of wind divergence that occur in the upper levels of the troposphere. [1] The formation process of a low-pressure area is known as cyclogenesis. [2]
The low pressure system eventually loses its warm core and becomes a cold-core system. [ 19 ] [ 17 ] The peak time of subtropical cyclogenesis (the midpoint of this transition) in the North Atlantic is in the months of September and October, when the difference between the temperature of the air aloft and the sea surface temperature is the ...
Key West saw its wettest February day in 13 years, recording close to 3.5 inches of rain Monday. The low-pressure system that brought these storms dropped as much as 4 inches of rain in some ...
Top weather news for Monday, Feb. 24, 2025: Florida is bracing for torrential rain and maybe even some severe weather as a low-pressure system moves in, while hundreds of milli… Fox Weather 1 ...
The White River in Augusta, Arkansas, northeast of Little Rock, has flooded "thousands of acres of farm ground," a local weather service office said in a weather alert Monday, adding: "Turn around ...
Most high-and low-pressure areas seen on weather maps (such as surface weather analyses) are synoptic-scale systems, driven by the location of Rossby waves in their respective hemisphere. Low-pressure areas and their related frontal zones occur on the leading edge of a trough within the Rossby wave pattern, while high-pressure areas form on the ...
A tropical cyclone is a storm system characterized by a large low-pressure center, a closed low-level circulation and a spiral arrangement of numerous thunderstorms that produce strong winds and heavy rainfall. Tropical cyclones feed on the heat released when moist air rises, resulting in condensation of water vapor contained in the moist air.
