A recent article in New Scientist reports the following claim made by Wenju Cai at CSIRO Melbourne.

Southern India is having a lot of rain as it goes into winter, having come out of the dry monsoon. This is only so during extreme El Niño, so it is a confirmation that the El Niño is huge

Does the claim indicate that a strong El Nino has a causal effect in extreme rainfalls in delayed monsoons? Has there been any historical evidence to backup this claim (for example the 1997-98 El Nino data)

  • @WanderingMind - The Southern Indian floods is not a case of delayed flooding. There are two separate monsoons in India. South West and North East. So onset was off by 6 days or so. –  Dec 04 '15 at 17:23
