The intertropical convergence zone is a broad trough of low pressure in equatorial latitudes. This is where the North-East and the South-East trade winds converge. This convergence zone lies more or less parallel to the equator, but moves North or South with the apparent movement of the sun. This is the cause of monsoon trough during the monsoon season and shifts the axis of the monsoon, and determines the spatial distribution of rainfall.
