Remarkable photos show ‘surreal’ fog shrouding Severn Bridge
Images appear to show weather phenomenon known as ‘temperature inversion’
Remarkable aerial photos show “surreal” fog shrouding the Severn Bridge.
The images, captured by a National Police Air Service helicopter on Tuesday morning, show a blanket of fog covering the crossing linking England and Wales.
The fog appears to have been caused by a weather phenomenon known as temperature inversion.
This happens when a layer of air sinks towards the ground, drying and warming as it goes.
This creates a warm layer of air that acts as a “lid” and traps cooler air near the surface, according to the Met Office.

Further images captured by Highways England cameras showed the bridge – which carries the M4 motorway – submerged in mist as the sun rises in the background.
