âA trough is an elongated area of low atmospheric pressure that can occur either at the Earth's surface or at higher altitudes.â âIn southwestern Australia, the hottest conditions are normally associated with low pressure troughs that direct east to northeasterly winds from the hot interior.â
The trough is the lowest point of a wave. To visualize this, recollect that waves come in sets. The trough is the lowest point, or the dip, between two waves in that set. The trough of a wave is the point on the medium that exhibits the maximum amount of negative or downward displacement from the rest position.
