What's that cloud? The more there is, the less you see

Last Thursday, we wrote about a beautiful valley fog image, sent in by Boris Srdos. You responded by sending in more wonderful images, so let’s take another look at your foggy shots!

Read the original piece of valley fog here.

The image above was sent in from Yorkshire over the weekend of fog once the sun had set. Fog can create beautifully aesthetic images, particularly for those living in upland areas.

Fog commonly forms into the evening and overnight periods under clear skies, because the Earth’s surface radiates heat back to space, allowing the ground to cool and subsequently the air above it.

As the air cools, it condenses and forms water droplets, particularly over moist ground, as we can see here.

On the flip side, we can see the process of fog “burning off” through the morning from Jacky Quirke’s scenic image in County Cork, Ireland.

Once the sun rises and starts heating the ground, this in turn warms the layer of air above it, allowing the water droplets within the fog to evaporate.

Of course fog doesn’t actually “burn off”, but Meteorologists commonly use this phrase as the process of fog dissipating through evaporation.

We also received this breath-taking shot below captured in Kaprun, in the Austrian Alps; a classic representation of fog blanketing the bowl of the valley.
