| <div class="definition"><div class="short_definition">Dynamically the same as the [[hydraulic jump]], but in meteorological contexts the equations are applied to a [[temperature inversion]] or to a system of two inversions.</div><br/> <div class="paragraph">The phenomenon of a pressure jump is thus a steady-state propagation of a sudden finite change of [[inversion]] height, in analogy to the [[shock wave]] in a compressible fluid. The [[prefrontal squall line]] has been interpreted as a pressure jump, with the [[cold front]] providing the initial pistonlike impetus. <br/>''See also'' [[compression wave]].</div><br/> </div>
