​Which one of the following is closely associated with westerlies?

(A) Furious fifties
(B) Boyle’s gas law
(C) Walker circulation
(D) Rossby waves

Choose the most appropriate answer from the options given below:

​(A) Furious fifties: This refers to the westerly winds found between 50° and 60° latitude in both hemispheres, known for their strong and persistent nature. These winds are closely associated with the westerlies.

(D) Rossby waves: Rossby waves are large-scale waves in the westerlies, which influence the movement of air in the atmosphere and the jet stream. They play a key role in the dynamics of the westerlies.​​​​

The Furious fifties refer to the strong westerly winds between 50° and 60° latitude. These winds are important in the movement of weather systems in the Southern Ocean and the North Pacific.

Rossby waves are large undulating movements of air in the westerlies and are responsible for the jet stream's behavior and the weather patterns in mid-latitudes.

Boyle’s gas law governs the relationship between the pressure and volume of gases and is unrelated to wind patterns like the westerlies.

The Walker circulation is primarily associated with the equatorial regions and affects the distribution of rainfall and temperature patterns in the tropics, not the westerlies.

Additional Knowledge:

(B) Boyle’s gas law: Boyle’s gas law relates to the behavior of gases and is not directly associated with westerly winds or atmospheric circulation.

(C) Walker circulation: The Walker circulation is an atmospheric circulation pattern associated with the tropics and equatorial regions, rather than the westerlies.
