FOG

Colourful leaves, cooler temperatures, early sunsets, and fog are without a doubt the most common autumn weather conditions. Do you know that fog is basically a cloud made of little water droplets? And where would you find the foggiest place on earth? Read more to find out.

FOG.

During autumn and winter, we can often see fog outside when we look out of the window.

Fog is basically a cloud¹ on the ground.  This special cloud is full of very small droplets² of water.  You can imagine it like this: in an Olympic sized swimming pool full of fog, there is only 1.25 litres of water.

Another word for fog is mist³, but there is a difference⁴.  If you can see less than 1,000 metres away, it is fog.  If you can see more than 1,000 metres away, it is mist.

A place called Grand Banks near Newfoundland in Canada is very foggy⁵.  There are 200 foggy days there every year.  The cold Labrador Current meets the warm Gulf Stream there, which creates fog.

Note: Olympic sized swimming pool: 50 m long, 25 m wide, 2 m deep, 660,430 gallons of water ± 2,5 mil.litrů vody (1 gallon = 3,8 l).
