The ITCZ is a zone of convergence at the thermal equator, where the trade winds meet. The ITCZ is a zone of convergence at the equator, where the trade winds meet. It is stationary throughout the year.
The trade winds converge in the region of the ITCZ, producing convectional storms that produce some of the world's heaviest precipitation regions. The ITCZ moves north and south of the equator depending on the season and solar energy received.
