SPOTTED: 12 rare but interesting weather phenomena

So, I read this article on Viral Nova which features 12 freaky and rare weather phenomena that will actually blow your mind, he he.

Swear, just keep scrolling down. These are natural occurrences but rarely can you see them, and if you see them, you're definitely either at bliss or in danger. So, do check out for the descriptions of each; the photos will surely be enough for you to recognize. 



1. Brinicle: Also known as ice stalactite, the brinicle forms beneath sea ice when a flow of extremely cold, saline water is introduced to an area of ocean water, being the undersea equivalent of a hollow stalactite or icicle. 



2. Tubular clouds: These clouds form due to changes in the temperature of clouds, add to that precipitation, which literally weighs down parts of the cloud formation causing bump appearances.


3. White rainbows (fog bow): They form when the water droplets in the air are about 0.02 mm in size. Light diffraction splits the spectrum combined to give a uniform white colo.


4. Catatumbo lightning: An atmospheric phenomenon in Venezuela, a catacumbo lightning occurs only over the mouth of the Catatumbo River where it empties; it can occur in areas like northwest Venezuela. When warm and cold fronts meet, it sets the condition for lightning to be made. Not only that, but nearby marshes emit methane gas, improving the electrical conductivity of the the cloud, which contributes to lighting strike production.


5. Moonbow: These “rainbows” form when there is mist in the air; they just happen in the moonlight. If you see it in person, these rainbows may seem white because of the very low brightness. However, if you catch them on camera with prolonged exposure you’ll be able to see these beautiful colors. 


6. Gloria: This one's a result of diffraction of light in the clouds or fog droplets; this occurs when a strong light source is behind you and the clouds reflect the light right back at you. 


7. Cappuccino coast (sea foam): The capuccino coast happens when algae and waste mix up in the water. These act as surfactants (like shampoo) and reduce the surface tension, creating bubbles and foam. 


8. Sprites, elves and blue jets: These are shapes and flashes of light which people see in the evening or night sky. Typically blue or red, these may result from electrical discharges in the atmosphere. 


9. Waterspouts: A waterspout is an intense columnar vortex (usually appearing as a funnel-shaped cloud) that occurs over a body of water. They are non-supercell tornadoes over water, and are typically not as dangerous as normal tornadoes. 


10. Fire whirls: Also known as fire devils, fire tornadoes or firenadoes, fire whirls are whirlwinds of flame which usually occur when intense heat and turbulent wind conditions combine. 


11. Morning glory: A rare meteorological phenomenon, the morning glory has been observed around the world, although no one knows why. These are usually associated with frontal systems crossing central Australia and high pressure in northern Australia. 


12. Volanic lightning: Also called dirty thunderstorm, this happens when lightning is produced during a volcanic eruption.
