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]
A clockwise spinning low-pressure area or cyclone of southern Australia. The center of the spiral-shaped cloud system is also center of the low. A low-pressure system over Iceland. In meteorology, a low-pressure area, low area or low is a region where the atmospheric pressure is lower than that of surrounding
A trough is an elongated region of relatively low atmospheric pressure without a closed isobaric contour that would define it as a low pressure area. Since low pressure implies a low height on a pressure surface, troughs and ridges refer to features in an identical sense as those on a topographic map. Troughs may be at the surface, or aloft, at ...
The Treasure Coast area is expected to receive marine impacts, such as higher wave heights, later in the week, a meteorologist said.
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 ...
The National Hurricane Center is monitoring a low pressure system off the NC coast and four other tropical disturbances.
A low pressure system has emerged over the eastern Gulf of Mexico and is projected to move northeast, according to the National Hurricane Center.. The latest tropical weather outlook predicts the ...
Average trajectory of a clipper. An Alberta clipper, also known as an Alberta low, Alberta cyclone, Alberta lee cyclone, Canadian clipper, or simply clipper, is a fast-moving low-pressure system that originates in or near the Canadian province of Alberta just east of the Rocky Mountains and tracks east-southeastward across southern Canada and the northern United States to the North Atlantic Ocean.
