Delhi witnessed an intense cold wave on Thursday,with the minimum temperatures plunging by 5 degrees Celsius below normal. The minimum temperature on Thursday was 4 degrees Celsius.
The India Meteorological Department (IMD) has sounded a warning for the coming week,when an intense wave of western disturbance is expected to hit the city on February 12 besides parts of Northwestern and Central India. A statement issued by the IMD on Thursday said the western disturbances have affected Jammu and Kashmir,Himachal Pradesh and Uttarakhand during the last four days,causing moderate to heavy snowfall mainly over Jammu and Kashmir.
This system and its induced upper-air cyclonic circulation has also caused light rainfall over the plains of Northwest India. The eastward movement of the western disturbance on Wednesday evening has also led to clear sky conditions over Northwest,West and adjoining Central India,which is a favourable weather situation for nocturnal cooling through radiation, an official from the IMD said.
The Met department said the strong,cold and dry north-northwesterly winds over Northwest and Central India have also caused a fall in Delhis minimum temperature by 5 degrees Celsius.
Director of the Met Department at IGI Airport,Dr R K Jenamani,said an intense wave of western disturbance is likely to affect Delhi region between February 12 and 16. There will be contrasting changes in the wind pattern,moisture and temperature conditions starting Sunday night,which may cause cloud cover and light rainfall at isolated places over Delhi,including the airport, Jenamani said.
According to the Met forecast,the day and night temperatures are likely to rise by 5-7 degrees,also making the conditions favourable for formation of dense fog between this period. The cold wave is likely to continue for the next 48 hours.
The official said cold waves are not unusual for February.
