A severe cold wave swept through Delhi on New Year's Day as the mercury plummeted to 1.1 degrees Celsius, the lowest in 15 years, and "very dense" fog lowered visibility to "zero" metres, affecting traffic movement.
On January 8, 2006, the city had recorded a minimum of 0.2 degree Celsius. The all-time record is minus 0.6 degrees Celsius registered in January, 1935.
The lowest minimum temperature recorded in January last year was 2.4 degrees Celsius, the India Meteorological Department (IMD) said.
Kuldeep Srivastava, the head of the IMD's regional forecasting centre, said "very dense" fog lowered visibility to "zero" metres at Safdarjung and Palam at 6 a.m.
According to the IMD, "very dense" fog is when visibility is between 0 and 50 metres. In case of "dense" fog, visibility is between 51 and 200 metres, "moderate" 201 and 500 metres, and "shallow" 501 and 1,000 metres.
The Safdarjung Observatory, which provides representative data for the city, recorded a minimum of 1.1 degrees Celsius, the lowest in January in 15 years.
