If the start of December has left you missing the winter chill in the air, there could be more disappointment in store for you. People across the country are likely to experience a warmer winter season this year due to the influence of a brewing El Nino in the Pacific Ocean. This will be the second consecutive year when the county is set to experience such a phenomenon. In a statement issued on Monday, the India Meteorological Department (IMD) addressed the fact that the 2018-19 winter season may be warmer than usual. It stated that the ongoing winter season is expected to last till February 2019 and will 'record above normal sub-divisional average temperatures across all meteorological sub-divisions,' as quoted in an Indian Express report. Speaking of the brewing El Nino conditions over the Pacific Ocean, a senior official from IMD Pune stated that the Equatorial Sea Surface Temperatures (ESSTs) recorded from over the Pacific Ocean are above normal. However, the atmosphere around the same area has not shown any significant variations correspondingly. He further added that it is likely that a weak El Nino develops towards February 2019, i.e by the end of winters. Current conditions indicate that the El Nino event could last for a short duration. The India Meteorological Department further identifies Core Cold Wave (CCW) zone across the country as Himachal Pradesh, Punjab, Uttarakhand, Jammu and Kashmir, Haryana, Rajasthan, Delhi, UP, MP, Chhattisgarh, Gujarat, Bihar, Jharkhand, West Bengal, Telangana and Odisha along with meteorological sub-divisions like Vidarbha, Saurashtra, Marathwada and Madhya Maharashtra. What is El Nino? El Nino is a climatic phenomenon that is known to impact global weather patterns. It occurs when abnormal warming takes place over the Pacific Ocean. Reportedly, El Nino is said to directly influence the rainfall pattern (monsoon) in the country. Whenever El Nino conditions prevail, the rainfall recorded that year remains below normal. It was during 2014 and 2015 when a strong El Nino was reported.
