Today’s satellite images show the small areas of the UK which have snow lying, as well as a number of interesting cloud formations.

The snow shows up very clearly over the Pennines and Scottish Borders, over the Isle of Wight, southeast England and the far east of East Anglia. False colour images are particularly good for identifying snow because the turquoise colour helps to differentiate between the white of the snow and the white of the clouds.

You can also see how the clouds have lined up on the wind across southern Britain – this is a great example of cumulus clouds forming ‘cloud streets’ when the winds at the height of the clouds are strong.

Over the sea to the north of the UK we can see more shower clouds moving towards us. Here we have a great example of the two different types of convection: open cell – where the individual clouds form circles over the sea; and closed cell – where the individual clouds have ‘clumped’ together across northern Scotland.

Aren’t satellite pictures wonderful.
