Explain how the formaton of tropical storms links to their location?

The “intertropical convergence zone” Known also by its initial letters ITCZ, this is a belt of converging trade winds and rising air that encircles the earth near the equator. This zone is a seedbed of tropical storms, for here the sun’s heat warms up air and water more than in any other area on earth.
Water from the ocean’s surface continually evaporates and rises with the warm air to form clouds. When conditions are right, several updrafts of warm air may combine, producing a chimney effect. As the chimney continues to grow, it will start spinning due to the rotation of the earth. Air pressure at the chimney’s bottom drops rapidly, drawing in still more air and moisture from outside the rotating column. It is similar to when water is sucked in at the bottom of a sipping straw. The warm, humid air may rise to a height of thirty to thirty-five thousand feet, where it encounters a blanket of cold air. Then it spreads out; the moisture condenses and begins falling as rain, whirling faster and faster with the winds as the storm develops.
