System-Relative Isentropic Vertical Motion
Where ? = system-relative vertical motion in ?bars sec-1
V= wind velocity on the isentropic surface
- P = pressure gradient on the isentropic surface
C is computed by tracking the associated vorticity maximum on the isentropic surface over the last 6 or 12 hours (one possible method); another method would be to track the motion of a short-wave trough on the isentropic surface
