Kolkata: Mercury fell to 13.9 ° C in Kolkata on Friday, the lowest season so far, even when the Met Office estimates further decline next week.
With the northwest wind it will be stronger, cool spells will continue until at least midweek next week, said the regional meteorological center (RMC).
The minimum temperature in the city is 14.2 ° C since Wednesday.
“It will be a chillier on Monday and Tuesday as further northwestern borders.
Temperature can plunge to 12 ° C.
But the minimum temperature can rise slightly on Saturday and Sunday,” said Director RMC G K Das.
With sliding temperatures, city air quality turns ‘poor’.
Across the station, the air quality hovered around poor (201-300), leaving the city that was panting for fresh air.
However, the monitoring station ambient air quality (CAAQMS) located on the University of Rabindra Bharati campus in BT Road has a surprised reversal – it is constantly very poor, but on Thursday, it increases for ‘poor’.
This is the first Chilly Mantra of the season that starts earlier this week with a Drop Threegree in mercury from 18 ° C to 15 ° C on Monday.
Since then, the minimum temperature remains below 15 ° C.
“Now, mercury will go down further,” said the watershed.
Cold was produced by snow snow in Jammu and Kashmir last week.
“It has triggered cool winds that are now flowing across the North Indian plains and have reached South Bengal.
Mercury has fallen across the North Indian state and Kolkata is no exception,” said the watershed.
Last week, the low pressure trough above bengal caused clouds and intermittent rain in Kolkata.
The minimum temperature is driven up to 19 ° C.
Cloud cover also carries a maximum temperature of up to 22 ° C in the city.
