A Freaky Fog Dome

It looks highly improbable but this fog dome in Denbighshire, north east Wales was featured on the BBC news after being photographed by a weather watcher on December 2nd, 2016.

Here is the story on this strange fog dome:

Early this morning Weather Watcher Hannah was out walking her dog in Tremeirchion, north Wales when she came across this very unusual dome shaped cloud of fog. 

“I just couldn’t believe how perfectly dome shaped it was. After about 10 minutes it started to flatten and looked like low lying cloud along the fields but over quite a big area, it was huge” she said.

Met Office and BBC Weather Centre Forecaster John West shares with us his thoughts on what could be causing this effect.

“This is a very unusual phenomenon, but the most likely explanation is that the “fog dome” has been caused by a source of heat close to the ground, possibly an agricultural building or a relatively warm pool of water. As the fog has formed in the valley this heat source has forced the fog to lift away from the ground into a dome as warmer air rises; like a hot air balloon.”


A French site has an image of a similar looking phonomena at a fountain:

Here is the Google translation:

Here is an image that shows an “identical” phenomenon …. Condensation … differences in temperature … an air saturated with water … wind … and voila!

That said, the main image is still impressive and for me … never seen in 50 years of existence. And so, I will leave this article in the category “Mystery” ..

No one expects the massive mysterious fog dome. Be ready. 😉

    1. It looks pretty crazy, alight, like a ghostly Hall of Justice or some alien phenomena. I wish she’d taken a few photos from the same spot as it dissipated.

  1. No one expects the mysterious massive fog dome – amongst it’s chief weaponry are such diverse elements as Fear, Surprise, Ruthless Efficiency, an almost fanatical devotion to the Pope and nice red uniforms – Damn!
    I’ll come in again!
