The last of the four major storm types is the supercell. We define a supercell as a thunderstorm with a deep rotating updraft (mesocyclone). In fact, the major difference between supercell and multicell storms is the element of rotation in supercells. Even though it is the rarest of storm types,

Air-mass Thunderstorm - Generally, a thunderstorm not associated with a front or other type of synoptic-scale forcing mechanism. Thunderstorm anvils may spread hundreds of miles downwind from the thunderstorm itself, It is attached to a supercell's general updraft and is oriented roughly parallel to the pseudo-warm front,

Like any thunderstorm, a supercell needs warm, humid air in the lower atmosphere, much colder air aloft and something to give the air near the ground an upward shove. To become a supercell, a thunderstorm needs strong winds coming from different directions at different altitudes high above the ground.

In the classic supercell scenario this change has its origin in differences in air mass characteristics associated with surface air flow. As precipation begins to fall out of the thunderstorm cloud, on the front or upwind side of the mesocyclone, a downdraft, called the Front Flank Downdraft, or FFD, is generated, along...
