  • “Satellite Imagery of Interest”: Intertropical Convergence Zone

  • Tuesday, 21st June 2016

A new Satellite Imagery of Interest is now available on the Observatory's website. The imagery shows the Intertropical Convergence Zone (ITCZ).

Intertropical Convergence Zone

The Intertropical Convergence Zone (ITCZ) is a belt of low pressure between subtropical highs of the Northern and Southern Hemispheres. It moves back and forth near the equator periodically once every year. Air streams converge over ITCZ which fuels development of convective activities and formation of most tropical cyclones. On 16 June 2016, global mosaic satellite imagery showed convective developments over ITCZ. ITCZ will move northwards in the next couple of months, and more tropical cyclones will be formed by a stronger Coriolis force.
