The Rainbow of Fire - flicker creative commons in different
sections of science and Yahoo! have witnessed some certainly curious natural
phenomena as the " tsunami of clouds "that occasionally
occurs in some coastal areas such as Panama City in Florida,
or the sea of waves that form over the Tide volcano on
Tenerife, or even that perfect moment that the photographer managed to
capture Tommy Eliassen in one image the Milky Way, the Northern
Lights and the passage of a meteorite.
But today we bring is undoubtedly one of the most unusual
weather phenomena and beautiful world.
The scientific term is accurate circunhorizontal
arc, although it is popularly known as "fire
rainbow" and illuminating the sky like a multicolored bonfire.
However, and although the name of "rainbow of
fire" illustrates very well their appearance in heaven, the truth is that
if we stick to reality should call them "rainbow ice
cream" since that is the true cause of its formation: small ice
crystals that reflect light the sun.
Curve circunhorizontal - flicker creative commons is a rare
phenomenon because it requires very special conditions for their appearance.
For that to happen we need the sun is above the clouds,
casting their light from above them.
It also requires that there are cirrus clouds of
hexagonal ice crystals arranged horizontally so that the light is
refracted when it passes through creating this symphony of colors in the sky.
To further hinder their formation, and the need cirrus ice
crystals circunhorizontales these arcs often occur in very cold
places such as Northern European countries, Russia and Canada.
Finally, these rainbows of fire usually have a short
duration, about an hour, another added difficulty makes these really unusual
phenomena in events to witness ... but who knows, maybe one day all the
following conditions and looking at the sky discover one of them.
