The northeast monsoon that caused the massive flooding in Tamil Nadu could extend for another two weeks due to the warming of the Indian Ocean, Joseph P V, former director of India Meteorological Department (IMD), said. The El Nino of 2015 has adversely impacted the monsoon rainfall in India and the side effects of warming of the surface temperature of the north Indian Ocean is strongly correlated with active cyclones, with a pre-dominant westward motion, he added.

“Rains are likely to continue for another two weeks. Normally, the northeast monsoon tapers off by mid-December. Excess temperature of 1 degree Celsius in the Indian Ocean is inducing more rains. This El Nino is one of the strongest seen in the last 100 years. El Nino warms the Pacific and the Indian Oceans disrupting the normal pattern,” Joseph, now professor emeritus in the atmospheric science department at Cochin University of Science and Technology, told FE. Joseph said Tamil Nadu, during the October 1 to December 15, received 64 % excess rains.

October to December is referred to as the northeast monsoon season over peninsular India.
