It's Not Very Clear...

A few mornings ago we woke up to a thick fog.


It wasn't just in our area.  It seemed that most of the country was shrouded in the fog.  Since it was everywhere, we decided to find out more about it.  We were surprised to find there to be so many different classifications of fogs, and determined that what we had must have been a freezing fog (as opposed to a coastal fog), which is related to the supercooled water concept that we learnt last week.  It might well have been a radiation fog, had it not been for the accompany feathery ice crystals that we saw on the window pane in the morning.

We have driven in thick fogs before so we remember what the hazard that the fog can present.  Therefore, it is good to heed the advice of the Met Office, even though what they're telling us is very much a matter of common sense.

There are two types of warnings for a fog:
(1) yellow


(2) amber

  1. I love how you guys are taking the opportunity to learn about all this weather we're having! J(8) had a scooter accident this week and we had to drive half an hour to the hospital at 615am on that foggy morning - visibility was very poor indeed!! (He's ok apart from a broken wrist and stitched lip, I'm pleased to say.)

    1. Oh no! I'm glad to know that J(8)'s accident is not too serious, although it must have hurt! Ouch! A broken wrist and stitched lips! Poor J(8)! I'm sure he's getting lots of treats and cuddles to help him recover... Poor boy! I hope he feels much better soon.

  2. Hwee,

    I wonder if mist is just a lesser form of fog. I keep meaning to find out! Or does fog have other substances in it apart from water? Now you've got me curious. Our village is often shrouded in thick mist. It sits in the hollows and gives an other worldly feel to where we live. We live in an elevated area and mists are frequent in all our neighbouring villages and towns. We get good at driving cautiously. Wouldn't want to bump into a kangaroo we haven't seen!

    1. That's a good question, Sue! As far as I know, both mist and fog are made up of water droplets only. The differences between them are:
      1) a mist gives a higher visibility than a fog;
      2) the water droplets in a fog are bigger and closer together than in a mist;

      As a result of condition (2), light cannot pass through a fog without the light being randomly scattered as it hits the droplets, hence giving low visibility.

    1. Thank you, Dawn. It's fun and very relevant to get to know our surroundings a little better. :-)

  5. I did not know about the fog warnings. We have been having a fair amount of fog as well before we got hit with a lot of snow.

    1. We don't normally look out for fog warnings. It's more a case of assessing how thick the fog is, then act accordingly. However, the more we learn about weather and the water cycle, the more we understand the interrelationships between one weather condition and another. :-)
