Recently, the Indian Meteorological Department (IMD) has predicted average minimum temperatures to be “warmer than average” in winters for most parts of the country.

  • India’s ‘core cold wave’ zone is expected to experience higher minimum temperature during winters.
    • A trigger for this phenomena is the warm surface waters of the equatorial Pacific ocean.
    • Core cold wave’ zone covers Punjab, Himachal Pradesh, Uttarakhand, Delhi, Haryana, Rajasthan, Uttar Pradesh, Gujarat, Madhya Pradesh, Chhattisgarh, Bihar, Jharkhand, West Bengal, Odisha and Telangana.
  • The warm winters in the country and overall rising global temperature is a sign of global warming.
    • India on an average is 0.5 degree celsius warmer than 50 years ago.
    • Rising temperatures lead to warmer than average ground temperatures and consequently a rise in minimum temperatures.
  • The global temperature is expected to rise 3.2 degrees celsius by the end of the century and intensify severe weather events.
