Which of the following is not correct regarding Inter Tropical Convergence Zone (ITCZ)?

  • A.In July, the ITCZ is located around 20°N-25°N latitudes (over the Gangetic plain), sometimes called the monsoon trough
  • B.The Inter Tropical Convergence Zone (ITCZ) is a low pressure zone located at the equator.
  • C.The Inter Tropical Convergence Zone (ITCZ) is a low pressure zone.
  • D.The Inter Tropical Convergence Zone (ITCZ) is a high pressure zone.

Answer: D

The Inter Tropical Convergence Zone is the belt near the equator where the trade winds of the two hemispheres meet. Because the air there is heated and rises, it is a zone of low pressure, not high pressure. It moves north and south with the sun, and in July it lies around 20 to 25 degrees north over the Gangetic plain, where it is called the monsoon trough. So the statements that the ITCZ is a low pressure zone, and that it lies at the equator or at those latitudes in July, are correct, while the statement that it is a high pressure zone is not correct. The answer is option D.
