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)
“As siblings we were inextricably bound, even though our connections were loose and frayed.... And each time we met, we discovered to our surprise and dismay how quickly the intensity of childhood feelings reappeared.... No matter how old we got or how often we tried to show another face, reality was filtered through yesterday’s memories.”
—Jane Mersky Leder (20th century)
“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)
