SHOOT :Isn't nature awesome...
A stack of altocumulus lenticularis clouds hovers over the Alpujarra Mountains in southern Spain, stained red by the rays of the setting sun.
Lenticular clouds are created when a stable layer of humid air is forced to rise over high ground, condensing its moisture into cloud.
When a cap cloud materializes, it tends to look like a hat, perched upon the mountain's head.
It forms when a stable air stream rises to pass over a peak, cooling as it does so.
These clouds look a bit like jellyfish floating in the sky.
Mammatus clouds (from the Latin for "udders") are associated with unstable, often stormy weather - though they can also be seen in relatively calm condition, long after bad weather has passed.
Looking like enormous waves breaking on the shore, this type of cloud is rare and fleeting - lasting no more than a minute or two.
The distinctive breaking-wave shape is caused by wind shear.
