The vertical extent of clouds formed by thermal lifting is determined by the moisture content and stability of the lifted air. In air containing a large amount of water vapour, more water is available and so a thicker cloud may be produced. In unstable air, the vertical currents extend to greater heights, tending to thicken the clouds. 2, record 5, English, - vertical%20extent%20of%20a%20cloud

Funnel cloud is a condensation funnel extending from the base of a towering cumulus or Cb [cumulonimbus], associated with a rotating column of air that is not in contact with the ground (and hence different from a tornado). A condensation funnel is a tornado, not a funnel cloud, if either a) it is in contact with the ground or b) a debris cloud or dust whirl is visible beneath it. 8, record 6, English, - tuba

The tornado and severe weather associated storm produce a recognizable radar echo structural organization resulting from an intense moist updraft. Some of these considerations are: ...
