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.
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.
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. There are various oceanic troughs on the ocean floors.
Sep 29, 2024 · 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 ‘equatorial trough’, where trade winds meet, is synonymous with the ‘intertropical convergence zone’.)

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.
