Layer Of High Cloud All We Got From Joaquin

For a week we had been wondering if hurricane Joaquin would send anything our way as it died a death somewhere over Europe this weekend. As it turns out, the main depression is filling off the northwest coast of Iberia, but one fragment of upper moisture from the former Category 4 hurricane has made it north and is doing its best to block out the sun.

This satellite image shows higher (colder) cloud as yellow and brown colours, the warmer (lower) cloud and terrain showing up as blue and pink (see the scale along the bottom). The main swirl of the remnant low can be seen as mostly low cloud circulating off the coast of Iberia.

The Eview image below shows a more natural picture, with the cold front showing up through Portugal. Liquid clouds appear yellower while ice clouds are whiter.


The Atlantic has gone quiet again now and high pressure looks set to influence our weather for the foreseeable future.
