Delhi reported its first foggy morning of the season on Monday, but the haze was milder than in other parts of North India through the week.

According to geo-analytics expert Raj Bhagat Palanichamy, who posted the image on social media, the curious gap in the blanket of fog was caused by something called the Urban Heat Island Effect.
Taken at 9:15 am on Wednesday, the image demonstrates how Delhi's urban sprawl, and the resultant heat retention, has created an island of residual warmth, thus clearing out the fog.
