Tamil Nadu’s coastline will receive erratic and extreme rainfall events through to 2030 due to the El Niño effect, a new joint study by the Department of Physics at Anna University and the Chennai Institute of Technology reveals. The findings follow unexpected bouts of rain across the state last month, flooding some streets with knee-deep water.

Researchers said the likelihood of heavy rains is extremely high in Tamil Nadu, which has a coastline of 1,076 km. The change in rainfall patterns is a consequence of global warming.

The study also raised concerns about the city’s “inadequate” infrastructure. After heavy rains in November, some streets in Chennai were flooded for a week. Experts say the infrastructure built over the past 15 years is only good at tackling the 5cm per hour rainfall, but will prove insufficient if heavy rainfall hits the city.

Earlier, in October, a report from the Center also highlighted the pattern of extreme rains across the country. He said while extremely abundant rainfall has increased, total monsoon rainfall has actually decreased by 6 percent over the past 60 years.

Another data compiled by the Indian Meteorological Department (IMD) has shown that while India’s annual precipitation appears ‘normal’ in its entirety, it is not evenly distributed. The meteorological body said heavy precipitation was recorded in some places while others recorded a deficit, making their average a “normal” amount of precipitation.

In 2021, India recorded healthy rainfall of 110 percent in June, an average of 93 percent in July, a low 76 percent in August and an outbreak of 135 percent flooding in September, according to data. of IMD.
