If you look very carefully, you can see a second, outer, rainbow forming. On this occasion nothing much happened with the second rainbow, or at least from where I was at the time. There hadn't been any rain locally but I guess there would have been a good shower nearby.

|Look carefully in the middle - the rainbow-like Circumzenithal arc|
Generally the arc will look like a smile but you still have to look carefully: these are the only photographs I have of Circumzenithal arcs and believe me, they're not easy to photograph.

|Mid summer Cirrus Uncinus|
Taken today, 14th July in the middle of a very warm and sunny spell of weather. Also spotted today:
Yes, I know the photograph below is not of some clouds as such. It was taken in a woodland area on the top of a hill shrouded in low cloud. So it is, sort of, a picture of a cloud - a nice misty scene early in the morning while it was still quite cool. Gradually the sun warmed up and the low level cloud melted away, leading to the pictures above during the afternoon.

The second was from the Brittany region and, as is often the case, the formation applied just after a rainy afternoon..

The Shard is claimed to be the tallest building in Western Europe at 310 metres; 1016 feet. Photographed here while still under construction it is clearly a dramatic addition to the London skyline and will provide a mixture of commercial and residential accommodation. I can only imagine the stunning views from the upper floors, unless they are shrouded in cloud that is!
Not too sure which variety; possibly Cirrus floccus.
I'm sure this is a Cirrus cloud but not too sure which variety. Cirrus clouds are always lovely to see as a sign of pleasant weather and can be at around 20,000ft.
Lower down there is (what appears to be) a string of Cumulus mediocris; a low hanging cloud which is sometimes grouped together by the wind. Otherwise earlier in the day they may have been Cumulus congests.
Taken early one evening from Birdlip Hill, Gloucestershire and looking west. The photograph above is one of my favourite cloud shots of all time: I like it for the simplicity and the soft colours blending in with each other. These clouds float around at about 2,000ft give or take a little.
These clouds are still forming as their bases haven't come together completely. They're common in warm fine weather and sometimes rise further to become Cumulus mediocris or cumulus congestus if there has already been rain. Happily this didn't happen on this day, they rolled by as we drove home in lovely weather.
The overall size of these can sometimes be stunning and you can almost see the internal convections taking place as the fluffy tops continue to bubble away.
I think this is a straight forward Cirrostratus arrangement. They are high level clouds and the wispiness is clearly seen against a clear blue sky.
We're looking at ice crystals forming, often ahead of an incoming depression with its lower air pressure - a sure sign of this happening is seeing these clouds grow and thicken - a sure sign of poor weather approaching. There are variations of these clouds including Cirrocumulus which is a sure sign of approaching wet weather.
The added bonus with this photograph are the vapour condensation trails from aircraft which have passed overhead, also known as "contrails".

If you happen to be in this cloud, you'll only get wet through the drizzle like moisture as these are unlikely to be effective in producing rain as they pass over. It's possible the clouds above may cause rain and this will fall through the lower level Stratus fractus clouds in order to confuse people like me!
This was taken on the Mediterranean coast of Spain during a pleasant holiday at the end of October. The weather was fine but a depression arrived during the next few days.
These are lovely high level clouds at around 20,000 feet and are gradually invading the sky because of the approaching lower pressure. They sometimes thicken and form into thicker strands, gradually joining up.
You can see they are not alone as there are some lower level clouds creeping in on the right hand side which are possibly Cumulus.
A dark brooding example somewhat exaggerated in monochrome which I occasionally use to photograph clouds. It's almost like a piece of Mahler's 5th symphony.
Although this is just a section, these can be huge structures towering vast heights into the sky. These often occur in the summer during hot stormy weather and often heavy rain storms will follow, possibly with hail or thunder. I love these!
These are energetic clouds arising from cumulus congests through powerful upward drafts which can develop into Cumulonimbus capillatus shown here.

Possibly a Altocumulus cumulogenitus cloud, taken at a distance on a summer's day in Bedfordshire, UK. I believe this is formed from a cumulus congests cloud as the cloud's upward growth is curtailed by the lower temperature in the higher atmosphere hence the "spreading out" effect.
