Where are the mid-latitude westerlies found?

• A. 0-30 latitude
• B. 30-60 latitude
• C. 60-90 latitude
• D. All latitudes

Answer: (B)

The mid-latitude westerlies are predominantly found between latitudes of 30 and 60 degrees. This region is characterized by prevailing winds that blow from the west to the east due to the Earth's rotation and the pressure differences created by the uneven heating of the Earth's surface.

In the mid-latitudes, the temperature gradient between the poles and the equator creates the jet streams and other significant wind patterns. The westerlies are particularly important for weather processes in this zone, influencing storm tracks and climate variations. These winds play a crucial role in the movement of weather systems across the globe, significantly impacting aviation by affecting flight routes and weather conditions experienced during flights.

In contrast, the areas near the equator (0-30 degrees) are dominated by the trade winds, which blow from east to west. The polar regions (60-90 degrees) experience polar easterlies, which are also distinct from the mid-latitude westerlies. The option stating "All latitudes" is too broad, as it encompasses regions where different prevailing wind patterns exist that are not classified as mid-latitude westerlies.
