Chapter 11, Problem 1QR

To determine

The ranking of hurricane, tropical depression, tropical storm, and tropical disturbance in the order of increasing strength.

Answer to Problem 1QR

The rank of events in the order of increasing strength is hurricane, tropical storm, tropical depression, and tropical disturbance.

Explanation of Solution

The disturbance which is caused in the winds due to low pressure that initiates weak wind surfaces and thunderstorms is known as tropical disturbance.

When the winds of the tropical disturbances gain the strength and flow more efficiently around and into the center of the growing storm, it becomes a tropical depression.

The wind with tropical depressions starts to spin with high speeds. When the speed of the wind increases more than 63km/hr, it forms a tropical storm.

When the speed of spinning wind increases further to 119km/hr, then it causes a hurricane.

Therefore, the ranking in the order of increasing strength is hurricane, tropical storm, tropical depression, and tropical disturbance.
