Southern India could continue to experience higher than normal rainfall leading to more flooding due to the effects of El Nino, a UN report has said, flagging concerns of states like Tamil Nadu battered by record-breaking showers this month.
The ongoing El Nino weather pattern -- a phenomena which sparks global weather extremes – currently gripping Asia and the Pacific is likely to be one of the strongest since 1998 and will continue into early 2016, according to the advisory.
The UN report, which asks regional cooperation for early warning, in-season mitigation and long-term adaptation strategies to curb risk, comes in the midst of the global climate negotiations in Paris, marked by acrimony and differences between the rich and developing nations.
Chennai, the country’s fourth most populous city, was severely hit by the extremely heavy rain, leading to extensive flooding in the Tamil Nadu for several days.
“While there is no detailed scientific investigation into whether there is a direct link between the 2015-2016 El Nino and Chennai city flooding yet, the consensus that strong El
Nino conditions has led to abnormal rainfall during the northeast monsoon season in South Asia indicates that El Nino had a part to play in the sequence of extreme weather events in India,” said the advisory by the by the UN Economic and Social Commission for Asia and the Pacific and the Regional Integrated Multi-Hazard Early Warning System for Africa and Asia (RIMES).
