"2019 to Be One of Strongest Indian Ocean Dipole Years On Record: Expert
By TWC India Edit Team16 September 2019TWC India
2. As someone who has been following IOD closely for many years, what are the multi-decadal trends you have noted? Is the phenomenon changing over time?
Strong IOD events tend to occur roughly every 10 years. The reasons for this are only being investigated. The countries that are strongly affected by IOD are those in the eastern Indian Ocean (Indonesia to Australia) and equatorial Eastern Africa, where IOD leads to severe lack of rainfall. Moderate impacts are found over portions of India up to southern Iran. We have also found that IOD can lead to excessively warm (southern hemisphere) spring seasons over central portions of South America (e.g. Bolivia).
3. Coming to 2019, how have IOD values moved since the beginning of the monsoon season, and where do you think they are headed from here?
IOD usually manifests first around early summer and strengthens to a peak in late fall. The current IOD is also following this pattern and has significantly strengthened during August. In fact, it is now very similar in its strength to one of the strongest IOD events in recent decades, that of 2006. [That year, too, a resurgence of rainfall in August across central and western India helped overcome an overall monsoon deficit, but left other parts dry.]
From available research, IOD impacts on Indian rainfall are expected to continue over Northwestern parts of India and may extend till October/November, when IOD reaches peak activity. We expect that the current IOD will develop to be one of the strongest on record."
And it was/Is.
"4. So what exactly can we expect if 2019 becomes one of the strongest IOD years of all time?
The dry spells over Indonesia, Australia and Singapore are strongly tied to the ongoing IOD. In fact, the Australian weather agency has been alerting Australians to adverse climate associated with IOD since early spring of this year. The weather agency of Singapore has, similarly, associated the dry spells over Singapore with IOD.
6. What are the gaps in scientists' current understanding of IOD at this point?
Although many studies have tried to understand the impacts associated with IOD, there are not many looking at the physical mechanisms through which IOD may drive these impacts. Unless we understand these, it is difficult to judge whether a particular impact is really attributable to IOD, and not a statistical artefact of the analysis. While the mechanisms by which an IOD intensifies is reasonably understood, it is not very clear what mechanisms or conditions leads to the initial development of an IOD; the same may be said about El Niño as well. Further, it is not known why we have intense IOD events roughly every 10 years. These are questions I want to find answers to.
7. Is global warming likely to have an effect on IOD?
It is difficult to say. Climate models used in global warming projections have certain deficiencies in simulating the structure of IOD and its relation to ENSO. Thus the future changes of IOD in global warming projections are not yet very reliable, but models are continuously improving and we hope to get a better idea of how global warming will affect IOD in the near future.

Climate Change is as normal as the sun rising in the east each morning.
We need to be good stewards of the resources here on earth... Stop.
The Co2 issue is a small driver in the future of a warming global climate... the sun's activity is many amplitudes more important...
Control the sun's activity.... then you have the key driver controlling earths climate...
Human activity is a "natural" part of this ecosystem..and and has a "significant impact on global weather..."
How "Evil" ends human history on tis planet... is a much more influential issue of concern... of course everything is related and connected...
The Christmas "Story" of Love, forgiveness, and humans needing to focus on overcoming greed and selfishness... is where our focus needs to be.
95% of the world now has Cellular phone service... with Satphone it is 100%.
Never have so many people been so well fed.
We need to be thankful for the blessings we have been given... and share them with those less fortunate.
Happy New Year... Have a Great 2020!!
MAY JESUS BE THE REASON FOR THE SEASON...
Love in our hearts... should mean we care for each other and share our blessings....
Have a wonderful day! God Bless you one and all!!!
