Given the proper environment, supercell thunderstorms may exhibit a tendency to split into two distinct storms: one rotating cyclonically, the other anti-cyclonically. Generally, the cyclonic storm remains dominant, whereas the anti-cyclonic storm rapidly shrivels and dies. However, these anti-cyclonic martyrs often make for good photography as they dissolve from bottom up, racing away from their cyclonic counterparts.

In the photo above, an anti-cyclonic split takes its last breath as the sun sets, lost in its own mammatus-laden anvil canopy. By the time the sun vanished for good, so had the storm.
