Weather radar is capable of measuring precipitation for several hundred kilometers in all directions because INSERT FIGURE 7-26. NO CAPTION
A) precipitation rarely occurs in one direction only
B) the curvature of the earth is minimal over these short distances
C) the radar transmitter/receiver rotates
D) there are usually a few dozen rain gauges within this distance
Question 2
The objective of cloud seeding is
A) to cause more droplets in a cloud to become supercooled
B) to convert some of the supercooled droplets in a cool cloud to ice and cause precipitation by the Bergeron process
C) to convert some of the supercooled droplets in a cool cloud to ice and cause precipitation by the collision/coalescence process
D) to enhance the evaporation of supercooled cloud droplets
