The Doldrums are characterized by low atmospheric pressure and very calm, light winds. Because the sun is directly overhead, the air is constantly heated and rises (convection). This vertical movement means there is very little horizontal pressure gradient at the surface, which is why the region is famously devoid of the steady winds found elsewhere. ANSWER: (B) Low pressure and calm winds
What are the characteristics of the Doldrums region? (A) Normal pressure and air subsidence (B) Low pressure and calm winds (C) Low pressure and air subsidence (D) Low pressure and gentle easterly winds

In the Doldrums, the primary atmospheric movement is vertical. As solar energy warms the ocean and land, the air becomes less dense and rises into the upper atmosphere. This creates a permanent low-pressure zone. Because the Trade Winds from the North and South converge here and rise, they effectively “neutralize” each other at the surface. This results in the “calm” that gives the region its name. However, this calm is frequently broken by violent, localized thunderstorms fueled by the rising, moisture-laden air, making the weather here both stagnant and unpredictable.
