The India Meteorological Department (IMD) has predicted that there will be no more cold wave in Delhi till January 4 and there might be a slight rise in temperatures.
However, the Air Quality Index (AQI) in Delhi continued to be in ‘severe’ category. According to the Delhi Pollution Control Committee (DPCC) data, the AQI in Anand Vihar was recorded at 418, at 426 in RK Puram and at 457 in Rohini early Thursday.
According to scientists, the easing of the cold spell over Delhi and several parts of north India is because of a change in wind directions on Tuesday from northwesterly, which brings cold winds from the Himalayas to the northern plains, to easterly, which brings moist air originating in Bay of Bengal from states such as West Bengal and Bihar.
Meteorologists said weather conditions were undergoing a transition, with a western disturbance affecting the region.
