New Delhi/Kanpur, Dec 29 (ANI): Cold wave in northern India showed no signs of easing up anytime soon as people in New Delhi and Uttar Pradesh continued to shiver with dense fog affecting normal life on Monday. The dip in temperatures is said to have been caused by snowfall in the Himalayas and has adversely impacted the upper half of the country. The cold wave has compounded problems of the homeless people and office-goers. People scheduled to travel via trains and flights also had to face a tough time as several trains and flights were delayed and rescheduled due to low visibility as a thick blanket of fog enveloped several areas in the capital.
