M Palawat, vice-president (meteorology and climate change), ‘Skymet Weather’, said that between January 9 and January 19, mainly due to cloudy weather and rain, there was no sunshine for a long time. He said that the rains between January 7 and January 9 increased the humidity in the air, which led to foggy conditions amid low temperatures. Due to fog and low clouds, cold conditions prevailed over large parts of the national capital and adjoining areas till January 16. From January 16, the day temperature again fell due to the influence of one western disturbance after another.
Palawat said that in January this year, the effect of Western Disturbance was observed six times in Delhi, while the effect of Western Disturbance is normal three to four times in a month. He said, “Delhi witnessed the effect of Western Disturbance three times between January 1 and January 9. Since January 16, three more Western Disturbances have affected the national capital. Its recent impact was seen on January 21.”
Due to cloudy sky and rain, the rays of the sun are not able to reach the earth, due to which the temperature of the day decreases. Clouds absorb the heat during the day, keeping the night temperature above normal.
