Temperature will plummet again with changing winds: Met

A cold wave that had most of northern Karnataka under its grip has abated for now, but it will not be long before these districts see another precipitous dip in temperatures, according to the meteorological centre here.

On Monday, most parts of the State recorded temperatures lower than the “normal” minimum and Belgaum was the coldest at 8.8 degrees Celsius. However, for a cold wave to be officially declared over a region, at least 50 per cent of the weather stations need to record temperatures below 10 degrees Celsius, said B. Puttanna, Met centre director. Last week, temperatures across most of north Karnataka dropped to single digits, with Belgaum recording a minimum of 6 degrees Celsius last Wednesday. But it would not be long before the wind direction changes from an easterly to a northerly one and for the temperature to dip again, Mr. Puttanna said. “This time the cold wave is likely to be even more severe than the one we experienced last week,” he added.

These weather conditions, , are typical of winter every year, Mr. Puttanna said. Another distinctive weather feature for this time of year is the extreme gap between maximum and minimum temperatures. In Bangalore for instance, the difference between the maximum and minimum was a huge 16 degrees. With skies that are totally devoid of cloud cover, and very little atmospheric moisture to buffer radiation, earth’s surface heats up much faster during the day, and loses heat equally fast at night, he said. In Bangalore, the minimum temperature was four to six degrees C. below normal on Monday, according to the weather bulletin.
