So far this month, the city has recorded 11 days with lower daytime temperatures (maximum staying under 17 degrees Celsius).
This is the highest since January 2015, who also saw 11 days like that.
With almost a week before the end of the month, it is expected that this winter can break the January 2003 record, which has seen 18 days like that.
R K Jenamani, senior weather expert in the Indian Meteorology Department, which was shown in January so far saw one of the longest spells of the ‘cold day’ condition.
At least eight to 11 days ‘cold’ has been recorded so far, both throughout the city or in several parts.

According to IMD, “cold day” is when a minimum temperature is below 10 degrees Celsius and the maximum of at least 4.5 degrees Celsius below normal.
In addition, Jenamani added, Delhi also recorded the highest rainfall for January in the last 122 years and very low sunlight or bright sky, making this winter “unique”.
“Delhi has experienced a unique winter at the moment.
There has been a lower mist formation in December and January, more cloudy days and the highest rainfall for January in the last 122 years, almost no sun since January 7, and also wrong One highest winter, “he said.
Explain the reason behind the unique phenomenon, weather scientists pointed to “warm December”, said while there was no Western disturbance until the month, then followed by a number of them.
Western disorders (WD) are high moisture air flowing from the Mediterranean Sea to East Himalaya through Iraq and Pakistan.
It leads to the snow on the hill and rain in the northern region, including Delhi.
“There are consistent and back-to-back western disorders from December 28 and so on until January 10, and once again on January 21.
When the gap between two more Western disorders, there is a cold spell.
Western disturbance on January 7 is a slower, which causes rain from January 5 to 8 and, therefore, the accumulation of moisture, clouds and fog lying, “said Jenamani.
He added that the phenomenon occurred on a very large scale over major geographical areas in North India.
“There are conditions that promote cooler spells, because the moisture makes the sun set and the temperature never remain normal throughout January,” Jenamani said.
He then shows that the whole winter season so far has also seen very low fog clocks, which means visibility of less than 1,000 meters.
“From December to January, we have seen only 45 days or 252 fog hours against 52 days or 570 hours of fog.
Last time, in 1991 that the total fog clock was low, at 42 days or 255 hours.
So, so far, fog hours This winter is the lowest in 30 years, “Jenamani said.
