Which of the following is considered as an interruption of the planetary winds?

Question

Accepted Answer

Monsoon winds are considered an interruption of the planetary winds because they are seasonal winds that reverse their direction completely with the change in seasons. Planetary winds, like the westerlies and trade winds, are relatively constant and blow in the same general direction throughout the year. Monsoons, on the other hand, are driven by differential heating of land and sea, causing a significant shift in wind patterns that disrupts the normal flow of planetary winds.

Here's why the other options are incorrect:

*   **Westerlies of Northern Hemisphere:** The westerlies are a part of the global planetary wind system. They are not an interruption but a component of it.

*   **Roaring forties:** The Roaring Forties are strong westerly winds found in the Southern Hemisphere between latitudes 40° and 50°. They are a characteristic feature of the planetary wind system (specifically, the westerlies) and not an interruption to it.

*   **Furious fifties:** Similar to the Roaring Forties, the Furious Fifties are strong westerly winds found in the Southern Hemisphere between latitudes 50° and 60°. They are also a part of the planetary wind system (westerlies) and not an interruption.
