Vasant Panchami festival, perceived to mark the departure of winter and the onset of spring, seemed to be right on time.
Sunny skies brought smiles on the faces of residents on Tuesday after three days of cloudy and chilly weather. The Met predicted three days of clear skies.
The most soothing weather development on Tuesday was a jump of almost 10 notches in the maximum temperature compared to Monday. The maximum temperature was recorded at 25.6°C on Tuesday. The minimum temperature of 8°C was also a notch higher from Monday.
Thanks to the Sun God that the continuous heating of the earth’s surface and the unhindered penetration of solar rays led to such a leap in the maximum temperature.
“The minimum temperature is expected to be around 9-10°C and the maximum temperature will remain around 24-25°C till Friday,” said Ashish Sen, the director of India Meteorological Department (IMD), Patna.
On being asked about the departure of winter, Sen said: “It would depend on the impact of any upcoming western disturbance on the state. If at all Bihar is affected by a western disturbance within a week leading to light rainfall then winter would depart by the end of second week of February. Otherwise, it would depart by the end of third week.”
The western disturbance — usually accompanied with rainfall during winter in this part of the country — is expected to change the wind direction from dry and cold westerly to moist and warm easterly. “This change in wind direction would lead to gradual rise in temperature conditions and lead to departure of winter,” he added.
Coming back to the overcast condition over the past three days, it was not cloud but a thick layer of vapour. The vapour was condensed moisture originating from Arabian Sea. Though it sustained for three days, weathermen claimed it had started weakening from Saturday.
“The cloud cover because of thick layer of vapour was lying between the heights of 600-1600m from the earth’s surface on the first day (Saturday). However, it had started to become shallow from Sunday. It was lying at the altitude of 600-1500m on Sunday and it further came down to 600-1200m on Monday. We were expecting that it would take a day or two to completely saturate but to our surprise it happened on Monday night,” said Sen.
