A region of cyclonic (counter-clockwise) curvature of winds in the atmosphere, located around a low-pressure area. Troughs are generally associated with cloudy, cool, unsettled, and wet weather.
Often recognized as a "Trough of Low Pressure". A Trough is an area of generally low atmospheric pressure. Troughs occur at all levels of the atmosphere. Upper level troughs drive airmasses toward the southeast usually causing stormy weather. Surface troughs often precede cold fronts causing a lowering of pressure and a wind shift.
charting term, also known as a bottom (eg. in charting prices, a trough is the point where the price bottoms before the pressure to buy pushes it back up). (See also Peak).
A trough of low pressure is indicated by isobars extending outwards from an area of low pressure. It has associated with a trough line which often indicated on a synoptic chart. The pressure at a point on a trough is lower than that at an adjacent point on either side of the line.
A low point or local minimum.
an area of low pressure that isn't "closed off" yet
a valley -- it is a low pressure area that has not developed a circular rotation
A surface low steered by the jet stream. Troughs bring generally cool, cloudy weather. When looking at a weather map, you can recognize a trough by its shape ().
The point where the price of a security bottoms out before climbing again.
An extended area of low atmospheric pressure.
A low pressure curve in the jet stream that steers storms around blocks.
an elongated relatively low pressure area between two high pressure areas.
A REGION OF UNUSUALLY LOW 500-HPA HEIGHT.
An elongated area of low pressure (where the air is rising) usually between two areas of high pressure. Troughs tend to deflect tropical systems away from the US coast.
Price low on a currency chart.
An elongated region of low pressure.
an elongated area of relatively low atmospheric pressure; the opposite of ridge
An elongated area of low pressure in the atmosphere.
A charting term, also known as bottom, referring to where a price troughs before the pressure to buy forces it upwards again. (Opposite of peak).
An elongated low-pressure system that generally stretches north and south.
An elongated area of low barometric pressure.
An elongated area of low pressure, often associated with a wind shift and showery weather.
An elongated area of low pressure at the surface or aloft.
(Thalwet) An elongated area of relatively low atmospheric pressure.
An elongated area of relatively low atmospheric pressure; also called trough line.
Trof], an elongated area of relatively low pressure that is typically associated with a cyclonic wind shift.
An elongated area of low pressure, running generally north-south.
An area of low pressure. Cyclonically curving winds.
With regards to charting, it is where the price bottoms out before climbing again.
An elongated area of relatively low atmospheric pressure, usually not associated with a closed circulation, and thus used to distinguish from a closed low.
