Description: This
picture from Sweden, titled Veins of
Heaven, depicts a natural science phenomenon called noctilucent clouds. These clouds mainly appear in high altitudes
during the summer time. Noctilucent
clouds from by water vapor going up to the higher colder atmospheres and condensing
with the dust particles that volcanic ash and decaying meteors give off. Then sunlight that is still below the horizon
shines through the clouds, giving off this vein like visual effect.
What questions does
this raise:
-Do these type of clouds have any precipitation element?
-Why do they mainly form in high altitudes?
-Why in the summer?
-Do they have an environmental purpose or is it just a
pretty display of light?
