Feel the chill as sky clears
- Fog lifts, signals mercury dip

Calcutta may have lost the chance to better its Celsius record this season, but the chill is poised to be back this week as the thick fog of the past few mornings makes way for bright sunshine.

“The minimum temperature, which was three degrees above normal on Sunday, will normalise by Monday. By Tuesday, it’s likely to dip further by one or two degrees,” said Gokul Chandra Debnath, the director of the Regional Meteorological Centre at Alipore.

After a cold spell that lasted six days the city had become relatively warmer over the weekend, with the minimum on Sunday rising to 17.3 degrees Celsius.

The Met office feels the renewed chill will last longer than the previous spell.

The weatherman blamed the fog for the sudden rise in the mercury.

“Fog in the morning blocks out the sun for several hours. Bright sunshine in the morning is crucial for a drop in the mercury during the evening and night,” said an official of the India Meteorological Department (IMD).

“Moreover, the fog over south Bengal was blocking the flow of the cold North Wind,” the official added.

The fog on Friday and Saturday morning, resulting from a high-pressure area over the Bay of Bengal, resulted in a relatively warm evening and night. The minimum, which determines the intensity of the cold in winter, is recorded around 2.30am.

“With the city getting relief from the morning fog on Sunday, the North Wind is expected to pick up pace from early on Monday,” said a weather scientist.

Is the sub-10 chill, experienced after seven years in the city on Tuesday and Wednesday, likely to make a comeback this season?

“With the minimum dropping to 12 degrees by Tuesday and conditions remaining favourable for a further decline, the chances for a return of the sub-10 chill around next weekend appear bright,” said a scientist of the Noida-based National Centre for Medium Range Weather Forecasting.

“Moreover, the fog over south Bengal checked the free flow of the North Wind, which further led to the rise off the minimum,” he added.

The foggy mornings on Friday and Saturday resulted in relatively warmer evenings and nights. The minimum, which determines the intensity of the cold in winter, is recorded at around 2.30 am.

The fog conditions eased out from Sunday morning and the North Wind flow is expected to shift gears from the wee hours of Monday.

“The fog conditions, which were the result of a high pressure area over the Bay of Bengal, have made way for bright, sunny mornings,” said a weather scientist.

“With the North Wind picking up pace from the early hours of Monday, the minimum is expected to tumble over the next two days,” he added.

Once restored, the chill is likely to stay for the whole week, assured meteorologists.

“The chill will return for all of the new week. The rest of this month should be sufficiently cold,” said the IMD official.

Is the sub-10 chill, experienced after seven years in the city on Tuesday and Wednesday, likely to make a comeback this season?

“With the minimum dropping to 12 degrees by Tuesday and conditions remaining favourable for a further decline, the chances for a return of the sub-10 chill around next weekend appear bright, as of Sunday evening,” said a scientist from the Noida-based National Centre for Medium Range Weather Forecasting.
