In situations where these phenomena propagate perpendicular to the direction of flow, the changes between the upstream and downstream values of parameters such as pressure, density, and temperature are given by the Rankine-Hugoniot relations.

When the collisionless variety of these phenomena propagate outward through the solar wind, they result in the heating of the surrounding plasma. Their arrival is signaled by geomagnetic disturbances. These dissipative phenomena also arise in the case of an object moving through a surrounding medium, such as air, with a Mach number greater than one. For 10 points, identify these phenomena in which characteristics such as pressure and density change discontinuously across a propagation, such as when an airplane exceeds the speed of sound.
