6. Trough (meteorology) - Wikipedia

   en.wikipedia.org/wiki/Trough_(meteorology)

   A trough is the result of the movements of the air in the atmosphere. In regions where there is upward movement near the ground and divergence at altitude, there is a loss of mass. The pressure becomes lower at this point. At upper levels of the atmosphere, this occurs when there is a meeting of a mass of cold air and another hot one along a ...
