Cloud inversions are a natural phenomenon that can be quite the view with the right circumstances.

On Thursday morning, a natural phenomenon known as cloud inversion could be seen over Fernie in southeastern British Columbia.

Cloud inversion, also known as temperature inversion, occurs when the temperature of the atmosphere warms as altitude increases causing smog in the air to be trapped and stay near the ground while the area becomes extremely foggy.

Without the hindrance of many clouds, the heat can move freely upwards, making for a spectacular view if one can rise high enough above the clouds – in this case, on hiking trails and biking from Mount Proctor north of Fernie.

Inversions become even more extraordinary in mountainous terrain. The density of cold air will force it to flow, trapping it in areas such as valleys, appearing as fog that can last for hours.

If one manages to exceed the necessary height, not only is the view clear and spectacular, but the mist stuck to the ground will appear like rocks in a pond, floating gently and swiftly through hills and valleys.

When reversals occur during thunderstorms, thunder can travel farther and sound much louder than under normal circumstances.
