The ITCZ is a zone of convergence at the thermal equator, where the trade winds meet. It is an area of high pressure. 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.
By Matt Rosenberg. Near the equator, from about 5Â° north and 5Â° south, the northeast trade winds and southeast trade winds converge in a low pressure zone known as the Intertropical Convergence Zone or ITCZ.Solar heating in the region forces air to rise through convection which results in a plethora of precipitation.he Intertropical Convergence Zone has been called the doldrums by sailors due to the lack of horizontal air movement (the air simply rises with convection). The ITCZ is also known as the Equatorial Convergence Zone or Intertropical Front.
