Frequent calms are most likely found in which area?

The doldrums, located near the equator, are known for their frequent calms and light winds. This area, which is characterized by a lack of significant air movement due to the convergence of trade winds from both hemispheres, can create conditions where vessels may find themselves stranded for extended periods without sufficient wind to sail. The phenomenon occurs because the warm air rises and cools, creating an area of low pressure. In contrast, trade winds typically exhibit consistent breezes, coastal areas might have variable winds influenced by topography and land-sea interactions, and stormy zones are characterized by turbulent weather and strong winds. Therefore, the doldrums stand out as the region most closely associated with calms, making this the correct choice.
