How can the Doppler Effect be used to determine if a storm is forming into a tornado?

What will be an ideal response?


Radar can determine the distance to a storm cloud. Since a tornado rotates (very rapidly) Doppler radar will measure the difference in velocity between the two sides of the storm to determine if it is rotating.

At what speed would a proton need to circle the Earth at a height of 1 000 km above the equator if the Earth's magnetic field is horizontal and directed north-south, with an intensity of 4.00 × 10^?8 T? (The radius of the Earth is 6 400 km and the charge and mass of the proton are q = 1.60 × 10^?19 C and mp = 1.67 × 10^?27 kg. Ignore relativistic corrections.)
