closer to the center of tropical cyclone, the eyewall also exhibits the appearance of a bar, and high lightning activity occurs within this central bar. after the bar passes through, the strongest winds and often the heaviest precipitation abruptly changes to calmer conditions within the eye, before the eyewall passes over again and the strongest winds arrive from the opposite direction.









































at sea, wind speeds typically reach level 8 on the beaufort scale while waves become drastically higher when the bar reaches overhead and squall lines begin to arrive.

torro scale









































the torro tornado intensity scale (or t-scale) is a scale measuring tornado intensity between t0 and t11. it was proposed by terence meaden of the tornado and storm research organisation (torro), a meteorological organisation in the united kingdom, as an extension of the beaufort scale.









































section::::history and derivation from beaufort scale.









































the scale was tested from 1972 to 1975 and was made public at a meeting of the royal meteorological society in 1975. the scale sets t0 as the equivalent of 8 on the beaufort scale and is related to the beaufort scale (b) by the formula:
