The Resonance Consultancy released its World’s Best Cities report 2021. For the sixth year in a row, London is ranked first as world’s best cities. India’s capital Delhi ranked 62nd in the list of worlds’ best 100 cities for 2021, only Indian city to feature in the list. Resonance Consultancy ranks the world’s best cities on the basis on 25 factors, including populations of more than a million, using a combination of statistical performance and qualitative evaluations by locals and visitors in 25 areas grouped into six core categories. The factors also includes the ongoing COVID-19 pandemic and the issues created by the novel outbreak, like income incongruity and unemployment. The report identifies the cities that are most desirable for locals, visitors, and businesspeople alike, rather than simply looking at livability or tourism appeal. Here is the list of world’s ten best cities for 2021. (Image: PTI)
Delhi reeled under a cold wave on Tuesday as icy winds sweeping through the city brought the minimum temperature down to 3.6 degrees Celsius, the India Meteorological Department (IMD) said.
The Safdarjung Observatory, which provides representative data for the city, recorded a low of 3.6 degrees Celsius as against 5.6 degrees Celsius on Monday.
The weather stations at Ayanagar and Lodhi Road recorded a low of 2.6 degrees Celsius and 2.7 degrees Celsius respectively, it added.
In the plains, the IMD declares a cold wave if the minimum temperature dips to 4 degrees Celsius. A severe cold wave is when the minimum is 2 degrees Celsius or less.
The IDM said the mercury may drop further by New Year''s Eve.
Cold wave conditions are predicted in parts of the city over the next three days, it said.
Kuldeep Srivastava, the head of the regional forecasting centre of the IMD, said a western disturbance led to "scattered to fairly widespread" snowfall in Jammu and Kashmir, Ladakh, Himachal Pradesh and Uttarakhand.
Cold and dry northerly/northwesterly winds from the western Himalayas have been barrelling through the plains, bringing the minimum temperature in north India down, he said.
On December 20, the Safdarjung Observatory had recorded a minimum of 3.4 degrees Celsius, the lowest this season so far.
Delhi''s air quality was recorded in the "poor" category on Tuesday morning. The city''s air quality index (AQI) was 237 at 9 am.
The 24-hour average was 253 on Monday, 396 on Sunday, 337 on Saturday, 357 on Friday, 423 on Thursday and 433 on Wednesday.
An AQI between zero and 50 is considered "good", 51 and 100 "satisfactory", 101 and 200 "moderate", 201 and 300 "poor", 301 and 400 "very poor", and 401 and 500 "severe".
Officials at IMD said favourable wind speed, up to 15 kmph, aided in dispersion of pollutants.
