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’.)
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.
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.
A trough is the result of the movements of the air in the atmosphere. In regions where there is upward movement near the ground and divergence at altitude, there is a loss of mass. The pressure becomes lower at this point.
Trough - an overview | ScienceDirect Topics. In subject area: Earth and Planetary Sciences. The troughs are interpreted as having formed by scouring, as a mixture of grains and liquid descended the sidewall and spread out along a nearly horizontal floor. From: Encyclopedia of Geology (Second Edition), 2021.
Trough: the lowest point of the wave. Wave height: the distance between the crest and the trough. Wavelength: the distance between two identical points on successive waves, for example crest to crest, or trough to trough.
In wave: Types and features of waves. …low point is called the trough. For longitudinal waves, the compressions and rarefactions are analogous to the crests and troughs of transverse waves. The distance between successive crests or troughs is called the wavelength. The height of a wave is the amplitude.
