At present, the minimum temperatures of Delhi are higher than Nagpur, Akola, Parbhani and Sholapur of Maharashtra. In fact, many districts of Madhya Pradesh such as Betul, Khargone, Chhindwara, Damoh and Umaria are also experiencing cooler nights than the capital city of India.
In Karnataka, many stations such as Bijapur, Dharwad, Haveri are witnessing low night temperatures than Delhi. In Rajasthan also, places such as Alwar, Churu, Sikar and Bundi are recording lower minimums than Delhi.
Usually during the winter months, northern parts of the country record much lower temperatures than the southern and central parts of India. But this unusual variation in temperatures can be attributed to two major factors i.e. clear sky and dry winds over most parts of West and Central India as well as over Karnataka.
Since the last few days dry winds are also blowing over all the areas. After sunset, earth releases its energy in the form of long wave radiation and bears clear, cloudless nights.
This energy escapes into the space resulting in fall of minimums, which is the case in the above-mentioned situation. But in contrast sky of Delhi remines partly cloudy. Moreover, the layer of smoke/ Haze and smog is also acting as a greenhouse effect.
The energy released is trapped between the surface of earth and cloud cover as well as smog layer resulting in increased minimums over Delhi.
Further, we expect this situation to remain grim. We expect temperatures to fall around mid of November until then pollution levels will remain high which will not let temperatures of Delhi to drop.
