17. “Beneficial competition” refers to a hail suppression strategy in which: a) the number of hail embryos is increased. b) microscopic particles are injected into a cloud’s downdraft. c) explosives are used to shatter the hailstones into small pieces. d) competing approaches to hail suppression are attempted, and the one that works the best is used.

Explanation / Answer

13. Answer c: The narrow zones where the accumulation of hail on the ground associated with the thunderstorms are known as hailstreaks or hailswaths. In this a significant updraft is required in the supercell of the thunderstorms

15. Answer c: Hailstorms cause notable damage to the automobiles, aircrafts. Hailstorm is a major hazard to flying and planes can be seriously damaged within seconds when the size of the hailstorm is greater than 0.5 inches. Also it is a nuisance for the driver of the automobiles during hailstorms. These hailstorms can dent, crack or even shatter the windshields and windows. With the advance warning the damage due to hailstorms to the automobiles can be significantly reduced.

16. Answer a: Property damage during the hailstorms is not a function of horizontal wind speed. Since vertical wind currents are important in formation of hailstorm. So this statement is incorrect.

17. Answer a: To suppress the formation of hailstorm this strategy is adopted. In this the seeding which increases the concentration of the ice embryo which allows competition between natural and artificial ice particles for the available liquid water. The supercooled distributes among all the ice particles which results in smaller size of the hailstorms and they melt to rain or sleet when falling to the ground.
