New Delhi: A day after several weather records were broken due to the impact of incessant rains, Delhi witnessed a January-like morning fog in the national capital. According to weather analysts, the fog in the morning was temporary condensation caused by a confluence of factors that included humid winds on Saturday morning that retained the moisture from the day before, and a cooler night due to clearing skies after several days of overcast weather. “The sky remained clear overnight, which cooled the ground. This is one of the reasons why the minimum temperature dropped rapidly to 13 degrees Celsius, which is usually seen in February. There was already enough moisture, which was further increased with moist winds in the morning. Therefore, the earth’s surface air condensed and this led to the formation of fog.Soon, the wind speed increased and its direction changed to north-westerly, which was dry and led to a drop in humidity levels,” said Mahesh Palawat of Skymet. After continuous decline for three days, the day temperature increased by 4-5 degrees Celsius on Saturday. It is expected to increase further. However, the IMD estimates that temperatures will still remain below normal and there is another possibility of rain on Monday.
