Tri-cellular circulation

Polar fronts are found at approximately 60 degrees North and 60 degrees South where air masses from the Polar and Ferrel cells meet.

• TRUE

• FALSE

Air masses diverge at the ITCZ at the equator.

• TRUE

• FALSE

Air rises at the poles, leading to divergence.

• TRUE

• FALSE

At 30 degrees North, a high pressure belt occurs where air circulation in the Ferrel and Hadley cell subside.

• TRUE

• FALSE
