Delhi to get colder next week
NEW DELHI: The minimum temperature in the national capital dipped to 4.2 degrees Celsius on Friday, even as calm winds led to a spike in pollution levels, weather experts said on Friday. The India Meteorological Department forecast that the temperature will rise slightly on Saturday, but will fall from Sunday evening.
On Friday, the minimum temperature recorded at Delhi’s Safdarjung weather station, considered the official marker for the city, was 4.2°C — three below the season’s normal. The maximum temperature, meanwhile, was 18.6°C — three below normal.
IMD scientists said the drop in temperature on Friday was caused because the fog layer in the early hours moved further away from the ground, which did not allow temperatures to rise during the day.
Kuldeep Srivastava, head of IMD’S regional weather forecasting centre, said, “The first reason for the temperature to fall on Friday was the rising of the fog
in the morning. Apart from this, the wind blowing over the city also carried high moisture content, which also kept temperatures low.”
Srivastava said the minimum temperature on Saturday will rise to around 6°C, but will fall from Sunday, till January 28.
A forecast by the National
Weather Forecasting Centre of the IMD said a fresh western disturbance hit the western Himalaya regions on Friday, because of which the wind direction in Delhi will change from northwesterly to easterly, which will cause the probable temperature rise in Delhi on Saturday.
“Rise in minimum temperatures
by 2-3°C is very likely during next 48 hours (January 23-24). A fall by 3-5°C during subsequent the subsequent three days (January 25-27) over most parts of northwest and central India is also predicted,” the NWDC forecast read.
After the western disturbance passes, Delhi will get colder from
Monday.
“On Monday, the minimum temperature is expected to be around 5°C, but by Tuesday it will fall further and reach around 4°C,” a senior IMD scientist said.
The change in the wind direction from north-westerly to easterly on Friday also causing slower winds, which led to a spike in pollution levels.
Central Pollution Control Board (CPCB) recordings show that the overall air quality index (AQI) on Friday was 364, in the ‘very poor’ zone. On Thursday, the 24-hour average AQI was 296, categorised as ‘poor’ in the CPCB scale.
