Indian Ocean Diapole... 4th August 

Positive IOD

• Temperature & Winds – The western tropical Indian Ocean becomes warmer than normal, while waters near Indonesia and Australia cool.
• Impact on India – A positive IOD frequently strengthens the Southwest Monsoon, bringing increased moisture over the Indian subcontinent which can help offset dry conditions caused by El Niño.

Currently in neutral phase. 

*IMD’s models, and some others, forecast a neutral dipole across the four monsoon months. 

*Australian Bureau of Meteorology allows a slim chance of a positive turn late in the season, in August or September. 

Positive IOD may ease impact of El Niño, improve monsoon prospects in the Peninsula Region. 

It can provide some relief by supporting better seasonal rainfall than what was expected under El Nino conditions.
