What is the impact of the Indian<\/b> Ocean Dipole(IOD)?<\/b><\/h2>\n

A positive IOD helps rainfall along the African coastline and also over the Indian sub-continent while suppressing rainfall over Indonesia, southeast Asia and Australia. The impacts are opposite during a negative IOD event.<\/span><\/p>\n

How much rainfall has India recorded this year till now?<\/b><\/h2>\n

India has collectively recorded 824 mm precipitation since the start of the southwest monsoon period on June 1, suffering a 19% deficit compared to its rainfall average for the period so far (1016.1 mm).<\/span><\/p>\n

Can positive IOD help the Indian Monsoon now?<\/b><\/h2>\n

Most models indicate that the positive IOD will likely take hold from September through November. But by this time, India’s southwest monsoon season would have tragically withdrawn from the subcontinent.<\/span><\/p>\n

However, the northeast monsoon season that reigns over South India from October to December could receive a boost in the initial rains if the positive IOD continues to stick around during that time.<\/span><\/p>\n

What will be the impact of Positive IOD on Australia?<\/b><\/h2>\n

In Australia, when a positive Indian Ocean Dipole (IOD) event occurs, it typically leads to: 1) Low rainfall from October to December 2) A delayed start to the monsoon season and 3) Reduced tropical cyclone activity.<\/span><\/p>\n

If an El Ni\u00f1o event were to also happen in 2023 alongside a positive IOD, these effects could become even more severe and potentially extend into the wet season.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
