Question

Which of these are true about the Easterlies?

• A. They are winds which blow from high pressure to low pressure areas between 25° and 35° parallels.
• B. These winds converge near the equatorial calm belt.
• C. In the northern hemisphere, they blow from the north-east towards the south-west direction.
• D. In the southern hemisphere, these winds blow from the north-west to the south-east.

Answer 1

Answer: (A), (B), (C)

The correct options are
A They are winds which blow from high pressure to low pressure areas between 25° and 35° parallels.
B These winds converge near the equatorial calm belt.
C In the northern hemisphere, they blow from the north-east towards the south-west direction.

In both the hemispheres, the Easterlies blow from the high pressurea area between 25° and 35° parallels towards the equatorial low pressure belt. Due to the rotation of the earth, their original direction changes. In the northern hemisphere, they blow from the north-east to the south-west whereas in the southern hemisphere they blow from the south-east to the north-west. These winds coming from both the sides converge near the equatorial calm belt.
