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 North Luzon Trough is a major geological feature located off the northern coast of Luzon Island between the Manila Trench and the Vigan-Agao Fault in the Philippines. [1] It is a well-developed forearc basin formed in front of the Luzon Volcanic Arc , an island arc system. [ 2 ]
A popular type of surface weather map is the surface weather analysis, which plots isobars to depict areas of high pressure and low pressure. Cloud codes are translated into symbols and plotted on these maps along with other meteorological data that are included in synoptic reports sent by professionally trained observers.
The depth of the trough is 5,700 meters. The East Luzon Trough formed during the Eocene and Oligocene epoch, 40–24 million years ago. [1] [2] [3] Immediately to the South of the East Luzon Trough is the Philippine Trench. They are separated, with their continuity interrupted and displaced, by Benham Plateau on the Philippine Sea Plate. [4]
August position of the ITCZ and monsoon trough in the Pacific Ocean, depicted by area of convergent streamlines in the northern Pacific. The monsoon trough is a portion of the Intertropical Convergence Zone in the Western Pacific, [1] [2] as depicted by a line on a weather map showing the locations of minimum sea level pressure, [1] and as such, is a convergence zone between the wind patterns ...
The Asiatic Low is a low-pressure trough which lies over southern Asia, during early summer. It is located roughly over India , heading over the Bay of Bengal . It is a major action centre for the Northern Hemisphere during that time of the year.

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]
