region.&nbsp;<\/li>\n\n\n\n<li>The IOD, in scientific terms,&nbsp;is a coupled&nbsp;<strong>ocean&nbsp;<\/strong>and&nbsp;<strong>atmosphere phenomenon<\/strong>, similar to El Nino\u2013Southern Oscillation (ENSO) but in the equatorial Indian Ocean.<\/li>\n\n\n\n<li>Through an extension of the Walker Circulation to the west and associated Indonesian throughflow (the flow of warm tropical
