Days break into new lows for a 7-year record

So far this winter has been quite unusual. Instead of low minimum temperatures, which conventionally gauge the chill factor, this time the maximum temperatures have been doing all the talking as far as cold is concerned, reports Avishek G. Dastidar.

So far this winter has been quite unusual.

Instead of low minimum temperatures, which conventionally gauge the chill factor, this time the maximum temperatures have been doing all the talking as far as cold is concerned.

This January has thrown up the chilliest days of this season with the difference between the maximum and the minimum temperatures getting narrower than usual.

This means, while the nights have been cold as they are supposed to be, the days, too,

have been chilly, giving

Delhiites no breather from the biting cold.

This month, there were 12 days-all but one day so far-when the difference between the minimum and the maximum temperatures was less than 10 degrees Celsius.

All these days, the maximum temperatures were between five and nine degrees lower than the normal mark.

On Wednesday, while the minimum was 8.1 degrees Celsius, a degree more than normal, the maximum was 16.2, five degrees below normal. And their difference is less by merely 8 degrees Celsius.

This is not a usual trend in January.

In January 2009, the entire month saw only six days when the gap between the day and night temperatures were less than 10 degree Celsius. In 2008, the number of such days was nil.

“With clear skies, the maximum temperature, which is basically the real measurement of how cold the day has been, remains in the neighbourhood of 20 degrees Celsius, which is either normal or slightly more,” said a senior official at the India Meteorological Department (IMD).

This year, the number of rain-bearing clouds in the form of Western Disturbance, was more frequent than last few years.

The result was overcast skies hiding the winter sun.

Consequently, the maximum temperatures could not climb much.

The lowest the day temperatures dipped was 12.1 degrees Celsius, a seven year low, on January 8. It was nine degrees below normal.
W
hat makes day chill unbearable is that most people are outdoors and the constant northwesterly winds make it cold. “There have been lower maximum temperatures in January. In the recent past, Delhi recorded the maximum temperature at 11.6 degrees Celsius on January 10, 1999, and 11.2 degrees Celsius on January 1, 2003. But this year’s is a seven-year record,” said the official.
