These tunnel-like cloud formations were visible in the counties of Oxfordshire and Galsterer on Thursday evening.

Where are the “cloud street”?
The heated air rises from the Ground up. At altitude the air cools, and condenseries in the cloud.
Sometimes in the lower atmosphere (the troposphere) there is a layer of warm air, which prevents air from earth to rise above. This phenomenon is called temperature inversion.
The cooled air from the ground, rests on the “wall” of warm air and instead of going up moves in the horizontal direction.
The cooled air falls back to earth in the places where it occurs, clouds are formed.
It all starts a cylindrical air circulation, which runs parallel with the wind direction. Because of this, clouds are a distinctive oblong shape, which reminds people of the street or the tunnels.
