In meteorology, a low-pressure area, low area or low is a region where the atmospheric pressure is lower than that of surrounding locations. Low-pressure areas are commonly associated with inclement weather (such as cloudy, windy, with possible rain or storms), [ 1 ] while high-pressure areas are associated with lighter winds and clear skies. [ 2 ]
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 term "cyclone" applies to numerous types of low pressure areas, one of which is the extratropical cyclone. The descriptor extratropical signifies that this type of cyclone generally occurs outside the tropics and in the middle latitudes of Earth between 30° and 60° latitude.
When meteorologists use the term: low pressure area, what are they referring to?There are quite a number of scientific terms commonly used in weather forecasting and low pressure is one of the ...
The Treasure Coast area is expected to receive marine impacts, such as higher wave heights, later in the week, a meteorologist said. Low pressure system has 30 percent chance to form. What will ...
A low pressure area formed in the south Bay of Bengal on October 20. On October 21, it organised into a well-marked low pressure area. It strengthened into a depression on October 22. [51] The same day in the evening, it had consolidated into a deep depression and moving in a west-northwest direction. [52]
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 back edge of the trough. Most precipitation areas occur near frontal zones. The word synoptic is derived from the Ancient Greek word συνοπτικός (sunoptikós), meaning "seen ...
The ninth depression and fifth named storm of the 2020 North Indian Ocean cyclone season, Burevi originated from a low-pressure area which formed on November 28. The system gradually became a depression on November 30, with the JTWC issuing a TCFA soon after. The depression then was upgraded into Cyclone Burevi the following day.
