A lee trough, also known as a dynamic trough, is "A pressure trough formed on the lee side of a mountain range in situations where the wind is blowing with a substantial component across the mountain ridge; often seen on United States weather maps east of the Rocky Mountains, and sometimes east of the Appalachians, where it is less pronounced."
Klepáč – one of six places in Europe where three watersheds meet Rhine–Danube watershed marker near Weitnau, Germany European watershed marker (Lviv Oblast, 2009). The divide continues northwards along the Albula Alps to Julier Pass, Albula Pass and Flüela Pass south of Davos, between the catchment area of the Rhine, which empties into the North Sea via the Netherlands, and the Danube ...
Ridge line extending to the left of the high pressure center (H). In meteorology a ridge or barometric ridge is an elongated area of relatively high atmospheric pressure compared to the surrounding environment, without being a closed circulation. [1] It is associated with an area of maximum anticyclonic curvature of wind flow.
Satellite image of Europe by night 1916 physical map of Europe Topography of Europe. Some geographical texts refer to a Eurasian continent given that Europe is not surrounded by sea and its southeastern border has always been variously defined for centuries. In terms of shape, Europe is a collection of connected peninsulas and nearby
A col, also called saddle point or neutral point, is in meteorology, the point of intersection of a trough and a ridge in the pressure pattern of a weather map. It takes the form of a saddle where the air pressure is relatively higher than that of the low-pressure regions, but lower than that of the anticyclonic zones. [1]
Shortwave trough with associated vorticity. A shortwave or shortwave trough is an embedded kink in the trough / ridge pattern. Its length scale is much smaller than that of and is embedded within longwaves, which are responsible for the largest scale (synoptic scale) weather systems.
Ridge and furrow is an archaeological pattern of ridges (Medieval Latin: sliones) and troughs created by a system of ploughing used in Europe during the Middle Ages, typical of the open-field system. It is also known as rig (or rigg) and furrow, mostly in the North East of England and in Scotland. [1] [2] [3]
At the southern end, the trough opens into the Porcupine abyssal plain. The Rockall Basin (also known as the Hatton Rockall Basin) is a large (c. 800 by 150 kilometres (497 by 93 mi)) sedimentary basin that lies beneath the trough. Both are named after Rockall, a rocky islet lying 301.4 km (187.3 mi) west of St Kilda.
