★ INFP. ♥ XineAnn's Poetry ♠ Archives ♣ For New Stumblers
Don't let love fool you;
It's not my first love.
Truth rocks my world,
from below and above.
~XineAnn
Thinking is more interesting than knowing,
but less interesting than looking. ~Goethe
For experience is the Soul's one and only nourishment ~James Hillman
Le coeur a ses raisons que la raison ne connaît point. ~Blaise Pascal
He who has lost his soul will be finding God anywhere, up above and down below, in here and out there, he will cling to every straw of love blown past his doorway as he stands waiting for a sign. ~James Hillman

Cloud of the Month for May
About this Cloud: Cumulonimbus
It is the beast of the lower atmosphere: roaring with deafening thunder; spitting shards of lightning and hailstones; whipping up twisting tornadoes and spawning dramatic cloud features, such as the udder-shaped mammatus clouds, cigar-shaped roll clouds and, well, wall-shaped wall clouds. Sometimes, the Cumulonimbus also produces something called a `microburst', which is best thought of as a cloud sneeze. Don't be deceived by the `micro' part: the sneeze of a Cumulonimbus is anything but restrained.
A microburst is a very localized column of air - up to 2.5 miles (4km) across - which shoots earthwards from the base of the cloud, spreading outwards with violent force upon reaching the ground. With gusting speeds of up to 150 mph, these winds can damage buildings, fell trees, and have been known to cause aviation crashes.
Much like human sneezes, microbursts can be either dry or wet. They do however last rather longer than ours: between 5 and 15 minutes. Along with chilly winds, the wet varieties produce sudden downpours. These can be quite heavy: enough to give you a cold, should you be in the firing line without the right clothing.

Yes, Virginia, there is a cloud of the month. This is so incredibly cool:
Halo, what's that?
There are many coloured arcs and rings, known as `halo phenomena', which can appear as the sunlight passes through tiny ice crystals in the sky. Over many parts of the world, these optical effects are most commonly seen through high clouds such as Cirrostratus or Cirrus. But the most dramatic displays of halo phenomena are often when the ice crystals are in the form of a ground-level cloud known as `diamond dust'. This is what produced the beautiful light display shown above.
Diamond dust is so named because of the way it sparkles in the sunlight. It is rather like mist, but consists of ice crystals rather than water droplets. When crystals form near ground level like this, they can grow more slowly than they do in clouds high in the sky. This can make them very pure from an optical point of view - clear like glass, rather than cloudy like ice cubes. If they also happen to form in the right shapes, the crystals in diamond dust can behave like countless microscopic prisms. These are what diffract and reflect the sunlight to form halo effects.
There are a whole range of possible arcs, circles and points of light that can appear. The fantastic display shown here, over Saalbach, in Austria, exhibits no less than five halo phenomena. The circle around the sun is called a `22˚ halo', while the points of light on either side of it are known as 'sun dogs', or `parhelia'. The line joining these with the sun (which hidden behind the trees) is called the `parhelic circle'. Finally, the arc appearing at the top of the image, just kissing the 22˚ halo, is known as an `upper tangent arc'.
