In meteorology, a "trough" refers to an elongated area of relatively low atmospheric pressure, often associated with the development of cloudy and unsettled weather. Troughs are typically seen in the upper levels of the atmosphere, notably in the jet stream, and are significant features that indicate disturbances in the weather.
