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.

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 atmospheric pressure at the center of a recognizable high or low-pressure area at any given instant, i.e. the highest pressure in a high or the lowest pressure in a low.

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 ...
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 ...
Sitrang originated from an area of low pressure near the Bay of Bengal offshore the Andaman and Nicobar Islands on 17 October. During its existence, the India Meteorological Department (IMD) designated as "high" the possibility of this low-pressure area turning into depression, according to its first bulletin. [ 5 ]
Severe Cyclonic Storm Dana [a] (/ ˈ d ɑː n ə /) was a strong tropical cyclone which affected the states of West Bengal and Odisha in India. [2] The third cyclonic storm and second severe cyclonic storm of the 2024 North Indian Ocean cyclone season, Dana formed from a low pressure area that the Indian Meteorological Department first monitored on October 20.
