Need Rain? Cloud Seeding Can Help

Sometimes cumulus clouds can be stubborn and have a difficult time producing a drop of rain especially where it is needed the most. However, there is an interesting way of modifying the weather to enhance the amount of droplets in a cloud. This particular weather modifier is known as cloud seeding.

Introduced in 1946, cloud seeding has been used as a way to enhance rain and moisture in places where water is scarce, such as Utah, which happens to be the second driest state after first-place Nevada. Utah receives only an average of 12.26 inches of rain in a year while Nevada barely received 10 inches. So cloud seeding has become a savior in curing the thirst for water in such dry areas.
