A region characterised in the barometric distribution by a system of closed isobars, having lowest pressure on the inside.

Sometimes called a low; an area of low pressure around which wind circulates in a clockwise direction in the Southern Hemisphere. (see also cyclone).

an area of low pressure and is associated with unsettled weather

a smaller body of low pressure whose circulation is anticlockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere flowing towards a low pressure centre

A deep business cycle trough.

A medium to large weather system, characterised by significantly low pressures in the centre, high anticlockwise winds and often considerable and persistent rain.

A region of low barometric pressure. Usually applied to the early stage of development of a tropical cyclone.

A travelling low pressure region

A mass of air with low atmospheric pressure.

A low area in a field where surface drainage away from the area does not occur.

An atmospheric pressure system resulting in a falling barometer reading, as with a cyclone (see cyclonic).

An area of low atmospheric temperature.

a region of low atmospheric pressure that is usually accompanied by low clouds and precipitation.

a low place of any size on the Earth’s surface, also may refer to a sedimentary trough or basin.

A region of low pressure surrounded by a series of closed isobars.

Relationship to Manganese Requirement"Low blood manganese levels may accentuate depression..."

1. In general, a point or limited area of locally lower elevation in a particular surface. 2. In meteorology, an area of low pressure; a low or trough. This is usually applied to a certain stage in the development of a tropical cyclone, to migratory lows and troughs, and to upper-level lows and troughs that are only weakly developed. This use of the term is most common in the European literature. See V-shaped depression. 3. Same as depression angle See wet-bulb depression, dewpoint spread.

a low place or hollow on a plain surface. [AHDOS

A low-pressure weather system; a "low". Also called a cyclone.

In meteorology, it is another name for an area of low pressure, a low, or trough. It also applies to a stage of tropical cyclone development and is known as a tropical depression to distinguish it from other synoptic features.
