- A trough is an elongated area of low atmospheric pressure, often associated with the movement of weather systems and mid-latitude cyclones. It typically represents a region where air is converging and rising, leading to cloud formation and precipitation.

Jun 22, 2024 · Troughs can be recognized by wavy lines that dip southward and have a “U-shape.”. On the other hand, ridges are characterized by lines that bend northward and have an “N-shape.”. By noticing these distinctive patterns, we can easily identify troughs and ridges on an upper air map.
Sep 29, 2024 · Quick Reference. 1 An extension of low atmospheric pressure from the central regions of a low-pressure system into a zone where generally higher pressure prevails. The term ‘trough’ is also, and in accordance with this definition, applied to equatorward meanders of the flow of the upper westerly winds over middle latitudes. (The ...
May 28, 2023 · The equatorward region of any meander is called a trough (pronounced like “troff”) and is associated with low pressure or low geopotential height. The poleward portion of a meander is called a ridge, and has high pressure or height.
In geology, a trough is a linear structural depression that extends laterally over a distance. Although it is less steep than a trench, a trough can be a narrow basin or a geologic rift. These features often form at the rim of tectonic plates.
What are some examples of a language boundary? European countries such as England, France, Spain, and Portugal; the border between Romance and Germanic languages that runs trough Belgium, France, Switzerland, and Italy
Apr 21, 2016 · Broadly speaking, troughs and ridges are properties of the pressure field and they can easily be seen on a weather map. Troughs are found near low pressure areas while ridges are found near high pressure. Below is an example of what they tend to look like.
These are valleys formed by the glacial processes of weathering, erosion and transportation. They have steep sides and flat floors. Unlike V-shaped river valleys, glacial troughs are straight as they have truncated any interlocking spurs which existed prior to glacial advance.
