System-Relative Isentropic Vertical Motion
Including C, the speed of the system, is important when:
* the system is moving quickly and/or
* a significant component of the system motion is across the isobars on an isentropic surface, e.g.,
if the system motion is from SW-NE and the isobars are oriented N-S with lower pressure to the west, subtracting C from V is equivalent to “adding” a NE wind, thereby increasing the isentropic upslope.
