Question
Exercise 19.2 - Tornado Wind Speeds
Assume that a tornado is on the ground but has no forward speed. Using the principle of
conservation of angular momentum, estimate the wind speeds of the tornado based on the
measured rotation of the winds in the mesocyclone. Use the space to the right of each problem
to work through the math. (1 mile=5280 ft)
Conservation of angular momentum relates the rotational velocity, v, to the radial distance, r,
from the center of rotation:
(mesocyclone)
= tornadol
(mesocydone)
V
(tornado)
1. radius of mesocyclone = 5 miles
rotational velocity of mesocyclone = 5 mph
radius of tornado = 1742 ft
rotational velocity of tornado =
2. radius of mesocyclone = 4 miles
rotational velocity of mesocyclone = 3 mph
radius of tornado = 528 ft
rotational velocity of tornado=
3. diameter of mesocyclone = 10 miles
rotational velocity of mesocyclone = 6 mph
radius of tornado = 528 ft
rotational velocity of tornado =
