King's Trough King's Trough King's Trough is an undersea trough in the Atlantic Ocean. It is located on the east side of the Mid-Atlantic Ridge, northwest of the Açores-Biscay rise and roughly 400 km NNE of the Azores. It is about 400 km long, running in a NW–SE direction. To the east it branches into the Peake Deep and Freen Deep. The center depth is 4500 m. Surrounding the trough are high ridges and seamounts, such as the Antialtair seamount and the Crum seamount complex. Various explanations for the complex have been suggested, ranging from compression a former plate-boundary, transform faulting or
Trough (meteorology) Tropical waves are a type of trough in easterly currents, a cyclonic northward deflection of the trade winds. Trough (meteorology) A trough is an elongated (extended) region of relatively low atmospheric pressure, often associated with fronts. Troughs may be at the surface, or aloft, or both under various conditions. Most troughs bring clouds, showers, and a wind shift, particularly following the passage of the trough. This results from convergence or "squeezing" which forces lifting of moist air behind the trough line. Unlike fronts, there is not a universal symbol for a trough on a weather chart.
