Be prepared for a colder winter this year, the Meteorological Department has said. “As per the early indications and because of good number of western disturbances this year, chances of a colder winters are very high,” Sunrendra Paul, director, Met department, said. The director also pointed out that the sharp nip in the air in the evening, compared to warm day time temperatures, was due to clear atmospheric conditions and low humidity.
The earth re-radiates the sun rays absorbed by it during the day time. If there is a cloud cover, the heat released makes for warmer temperatures on earth, but in clear weather, the re-radiated heat waves disperse faster, resulting in colder temperatures.
The maximum temperature on October 19 last year was 32 degree, while the minimum was 19.2 degrees. This year, however, the maximum temperature on Wednesday was 33 degrees, while the minimum temperature recorded was 16.9 degrees, a drop of 2.4 degrees.
