Which permanent wind blows between 30° South to 60° South latitudes ?

Question

Accepted Answer

The correct answer to the question "Which permanent wind blows between 30° South to 60° South latitudes?" is Option 3: Westerlies winds. Here is a detailed explanation supporting this answer:

1. **Explanation for Option 3 (Westerlies winds):**
   - The Westerlies are prevailing winds that occur in the mid-latitudes between 30° and 60° in both hemispheres. In the Southern Hemisphere, these winds blow from the northwest to the southeast. The Westerlies are driven by the rotation of the Earth and the temperature differences between the equator and the poles. They are a key component of the global wind pattern and play a significant role in influencing weather and climate in these regions. The Westerlies are particularly strong in the Southern Hemisphere due to the lack of large landmasses, which allows them to flow more freely over the ocean.

2. **Explanation for why other options are incorrect:**

- **Option 1 (South-East trade winds):**
     - The South-East trade winds are found between the equator and 30° South latitude. They blow from the southeast towards the northwest. These winds are part of the Hadley cell circulation and are not present in the 30° to 60° South latitude range, making them incorrect for this question.

- **Option 2 (Polar Easterlies):**
     - Polar Easterlies are cold, dry prevailing winds that blow from the east to the west between 60° and 90° latitudes in both hemispheres. They originate from the polar high-pressure areas and are not found in the 30° to 60° South latitude range. Therefore, they do not apply to the specified latitudinal range in the question.

- **Option 4 (North-East trade winds):**
     - The North-East trade winds occur in the Northern Hemisphere between the equator and 30° North latitude. They blow from the northeast towards the southwest. Like the South-East trade winds, they are part of the Hadley cell circulation and are not relevant to the 30° to 60° South latitude range.

In conclusion, the Westerlies winds are the correct answer as they are the prevailing winds that blow between 30° South to 60° South latitudes, while the other options refer to wind patterns that occur in different latitudinal ranges or hemispheres.
