The Doldrums is a “no-wind” belt located near the equator. In this region, the air is mostly moving upward due to heat rather than sideways along the ground. Because there is very little horizontal wind, sailing ships in the past would often get stuck there for weeks. It is a place characterized by calm seas and sudden, rainy thunderstorms. ANSWER: (B) Tropical no-wind belt
What is the Doldrums? (A) Subtropical wind belt (B) Tropical no-wind belt (C) Tropical wind belt (D) Tropical wind deflection belt

The Doldrums, scientifically called the Intertropical Convergence Zone (ITCZ), is a unique belt where the trade winds from the North and South meet. Because the sun’s heat is so strong at the equator, the air rises almost vertically. Since wind is technically the horizontal movement of air, a lack of horizontal movement means there is “no wind.” Sailors named this area the Doldrums because they felt “dull” and stuck while waiting for a breeze. For students, it is important to remember that even though the air feels still, it is actually moving very fast—straight up!
