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 ...
The weather charts in some countries or regions mark troughs by a line. In the United States, a trough may be marked as a dashed line or bold line. In the UK, Hong Kong [1] and Fiji, [2] it is represented by a bold line extended from a low pressure center [3] or between two low pressure centers; [4] in Macau [5] and Australia, [6] it is a ...
Map of pressure systems across North America. A pressure system is a peak or lull in the sea level pressure distribution, a feature of synoptic-scale weather.The surface pressure at sea level varies minimally, with the lowest value measured 87 kilopascals (26 inHg) and the highest recorded 108.57 kilopascals (32.06 inHg).
One type of intense surface low-pressure system you might have heard of before is a "bomb cyclone". ... You'll often see multiple circular lines surrounding a surface low on weather maps, as shown ...
The Treasure Coast area is expected to receive marine impacts, such as higher wave heights, later in the week, a meteorologist said.
The National Hurricane Center is monitoring a low pressure system off the NC coast and four other tropical disturbances.
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.
Near the strong wake low, strong winds and a temperature spike were recorded. A wake low, or wake depression, is a mesoscale low-pressure area which trails the mesoscale high following a squall line. [1] Due to the subsiding warm air associated with the system's formation, clearing skies are associated with the wake low.
