Intertropical Convergence Zone Explained 🌍

Short answer: The dynamic belt near the Equator, where the trade winds of the Southern and Northern hemisphere converge cancelling each other out.

Sailors of the past era of the sailing ships called this belt the doldrums or the calms due to the risk of being caught in this windless area relying on currents alone to progress. A ship could be becalmed here for weeks if unlucky.

The intertropical convergence zone is a low pressure belt, where the solar heating is at its zenith thus dragging in the trade winds.
