Document Summary
A supercell has one updraft that is displaced from two downdrafts. Downdrafts names after where they are in the storm: forward or rear flanks of the storm. Everything needed for single - and multicells, except one more ingredient: vertical wind shear: 1. Leads to updraft and downdraft being in different locations: 2. Another correct answer: a tornado is just wind. The tornado is the wind circulation: tornado you see is manifestation of that wind. Accompanying this circulation, cloud droplets form because tornadoes have very low pressure. Separately, winds from a tornado suck up dirt, dust, and other debris debris cloud. A funnel cloud refers to a circulation with a condensation funnel that is not in contact with the ground. A tornado begins with a surface wind circulation: often no condensation funnel or debris cloud. Developing: winds increase, condensation funnel develops, maybe damage/debris. Mature: tornado is a t its strongest and widest: usually vertically upright and dark in appearance from debris.
