Lee trough
NettetA lee trough is a zone of low atmospheric pressure that forms on the leeward side of a mountain range. It occurs when air flows over a mountain range and descends on the leeward side, creating a region of low pressure. The combination of this descending air and the Coriolis effect leads to the formation of a trough.

NettetThe major features of this conceptual model are: (1) the development and contraction of the lee trough in association with low-level frontogenesis, (2) the development of an occlusion-like structure as the lee trough moves across the plains, (3) the lack of a well defined warm-sector during the evolution of the cyclone, and (4) the slow … Nettet20. jan. 2024 · The gentle slope is defined as the stoss side and is bounded by the crest line and the stoss trough. The steep slope of the dune is defined as the lee side and is bounded by the crest line and the lee trough. The lee side of the dune indicates the migration direction of this structure.
NettetA trough is an elongated region of relatively low atmospheric pressure, often associated with fronts. [1] A very large trough (about 8000 km or more) crosses the North Atlantic Ocean from North East to South West. The elongated cloud is surrounded by two big areas of higher atmospheric pressure, clearly shown with no clouds at all. Nettet25. apr. 2012 · lee trough. ( Same as dynamic trough.)
