Intensity
A TVS can be measured by gate to gate wind shear, which is the change of wind speed and direction across the two gates of inbound and outbound velocities. Gates are the individual pixels on the radar display. For example, if the inbound velocity is −48 knots (−89 km/h) knots and the outbound is 39 knots (72 km/h), then there is 87 knots (161 km/h) of gate to gate shear. The impressiveness of a TVS not only has to do with the strength of the gate to gate shear, but it also incorporates the size and depth of the TVS, and the strength of any surrounding mesocyclone, among other things.

Famous quotes containing the word intensity:
“A man of my spiritual intensity does not eat corpses.”
—George Bernard Shaw (1856–1950)
“Many women are surprised by the intensity of their maternal pull and the conflict it brings to their competing roles. This is the precise point at which many women feel the stress of the work/family dilemma most keenly. They realize that they may have a price to pay for wanting to be both professionals and mothers. They feel guilty for not being at work, and angry for being manipulated into feeling this guilt. . . . They don’t quite fit at home. They don’t quite fit at work.”
—Deborah J. Swiss (20th century)
“We may say that feelings have two kinds of intensity. One is the intensity of the feeling itself, by which loud sounds are distinguished from faint ones, luminous colors from dark ones, highly chromatic colors from almost neutral tints, etc. The other is the intensity of consciousness that lays hold of the feeling, which makes the ticking of a watch actually heard infinitely more vivid than a cannon shot remembered to have been heard a few minutes ago.”
—Charles Sanders Peirce (1839–1914)
