Cold wave to persist for next 2-3 days

With the city experiencing a cold wave for the past 10 days, citizens have a reason to cheer as the temperature is expected to rise after the next 2-3 days, according to the India Meteorological Department (IMD).

“A minimum temperature of seven degrees will persist for the next 2-3 days after which it is expected to rise,” said Medha Khole, deputy director general (weather forecasting), IMD. The minimum temperature of the city has been hovering around 7 degrees Celsius for the past week after a sudden dip was recorded in the temperature from 13.6 degrees Celsius to 9.9 degrees Celsius on December 7.

The mercury dipped to a further 6.9 degrees Celsius last Monday, the season’s lowest and also the third lowest recorded temperature in the last 10 years, according to the IMD officials. The current temperature in the city is said to be almost four degrees below its normal temperature.

Meanwhile, the cold wave has been accompanied by a massive swing in the maximum and minimum temperature. The maximum temperature recorded in the city was 30.6 degrees Celsius, which is two degrees above normal. The average difference in the minimum and maximum temperatures of the past week has been around 22 degrees Celsius.

IMD data reveals that temperature is seen to remain high throughout the day before it dips during night time and continues to remain low till early morning.

When asked about the reason behind the fluctuation, Khole said, “It is mainly due to the clear skies. As there are no clouds in the sky, maximum amount of radiation reaches the surface of the earth leading to a rise in the daytime temperatures. Also, clear skies lead to maximum outgoing radiation during nights, which is the reason behind the sudden dip in the temperature during nights.”

“A drop in humidity is also responsible for the persisting cold weather and dryness in the atmosphere,” she added.
