In other to explore the relationship between the rainfall seasonal variability and the IOD modes, is it statistically correct to use SPI if not, what is the best option to represent the rainfall data and also the statistical tool that fits this kind of analysis? Thank you.
The Australian Bureau of Meteorology uses IOD in their short and long term climate forecasting. They use relatively state of the art tools. You might send them an email at [email protected]. Also take a look at http://poama.bom.gov.au/climate/iod/
Hi Mr Ezedigboh.
There are several papers in the literature as already mentioned above.
I would like to add a paper of ours on East Africa rainfalls that has just been accepted for publication on the Quarterly Journal of the Royal Meteorological Society. Without pretending it to be general, I believe you can start from it to make up your mind on analysis tools and to inspect other results in the literature.
Hope it helps.
Cheers,
Vincenzo Levizzani
