Definitions for "Trough"
Any channel, receptacle, or depression, of a long and narrow shape; as, trough between two ridges, etc.
The transverse section of a cyclonic area where the barometric pressure, neither rising nor falling, has reached its lowest point.
The bottom between two waves.
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).

High-temperature (180+) concentrator with one axis-tracking.
A colloquial and descriptive name of the parabolic cylinder (surface of constant parabolic cross-section) used for collecting solar radiation along the focal length. Trough systems follow the path of the sun by pivoting on one axis (typically East-West or North-South), using shiny parabolic troughs to heat the collector fluid that passes through a tube at the focus. Below is an illustration from the Solar Radiation Data Manual for Flat Plate and Concentrating Collectors.
a solar tracking mirror, either one or two axes, that generally reflects sunlight onto a linear receiver that is perpendicular to and is in alignment with the sun and the central axis of the linear parabolic mirror
The point in the business cycle when an economic contraction reaches its lowest point before turning up. Contrasts with peak.
A point in the business cycle corresponding to the end of the slowdown and the beginning of expansion.
The lower turning point of a business cycle; the point at which the economy turns from contraction to expansion. Back to the top
