wall cloud

Some wall clouds have a feature similar to an "eye".

The wall cloud was large and showed clear signs of rotation.

Continued development took place over the following day as a well-defined wall cloud developed within the system.

The wall cloud tends to form closer to the center of the mesocyclone.

The wall cloud withers and will often be gone by the time the tornado lifts.

People seeing a shelf cloud may believe they have seen a wall cloud.

Often tornadoes are preceded by a thunderstorm and a wall cloud.

Rising scud may condense and organize into a wall cloud.

Rotating wall clouds are the visual manifestation of a mesocyclone.

Tornadoes may also occur without wall clouds, under flanking lines, and on the leading edge.

The wall cloud showed no signs of rotation and dissipated shortly after being spotted.

The sky was filled with jets and prop fighters climbing like the wall clouds of a hurricane.

The wall cloud is a spinning layer of clouds descending from the mesocyclone.

Tornadic wall clouds tend to have strong, persistent, and warm inflow air.

As the updraft rotates, it may form what is known as a wall cloud.

Wall clouds form when rain-cooled air from the downdraft is pulled into the updraft.

As the wall cloud descends, a funnel-shaped cloud may form at its center.

From eyewitness accounts of the wall cloud, circulating air may have reached the ground without a visible funnel.

However, wall clouds do not always rotate.

However, scud precede wall clouds, which often form from rising scud.

Visual cues such as a rotating wall cloud or tornado may also hint at the presence of a mesocyclone.

As this air continues to rise, it becomes more saturated with moisture, which results in additional clouds, usually in the form of a wall cloud.

The rotating wall cloud had broken.

Tornadogenesis is most likely when the wall cloud is persistent with rapid ascent and rotation.

Greg and Carol had taped the entire development sequence, from wall cloud to rope-out, at close range from the ground.
