In which month is the ITCZ positioned north of the equator?

• A. January
• B. April
• C. July
• D. October

Answer: (C)

The Intertropical Convergence Zone (ITCZ) is a significant meteorological feature characterized by the convergence of trade winds from the Northern and Southern Hemispheres. Its position shifts throughout the year due to the varying angle of the sun and resulting heating of the Earth's surface.

In July, the ITCZ usually migrates north of the equator as the Northern Hemisphere experiences summer. This northward movement occurs as landmasses, particularly in Africa and parts of Asia, warm up more than water bodies, prompting convection and resulting in the ITCZ settling into areas with rising warm air. The position of the ITCZ influences weather patterns, including increased precipitation in tropical regions.

During other months such as January, April, and October, the ITCZ is closer to or at the equator, generally having a more equatorial positioning. Therefore, July is recognized as the month when the ITCZ is distinctly north of the equator, making it the most accurate choice.
