Although it looks like a sea of blood this is actually caused by a high concentration of algae that accumulate rather rapidly. While some of these can be relatively harmless, others can be harbingers of deadly toxins that cause the deaths of fish, birds and marine mammals. In some cases, even humans have been harmed by red tides though no human exposure are known to have been fatal.
Light Pillars
Light pillars appear as eerily upright luminous columns in the sky, beacons cast into the air above without an apparent source. These are visible when light reflects just right off of ice crystals from either the sun (as in the two top images above) or from artificial ground sources such as street or park lights. Despite their appearance as near-solid columns of light, the effect is entirely created by our own relative viewpoint.
Something I think we have all seen before, a red moon, blue moon etc and how eerie they are! When the moon appears lower on the horizon, rays of light bouncing off it have to pass through a great deal more of our atmosophere which slowly strips away everything but yellows, oranges and reds.
Natural phenomena that happen only in places between Chile and Argentina. It's a phenomena of snow in the high surface that pointed. It's caused by strong wind in the Andes mountains.
Venezuela's Everlasting Storm
The mysterious "Relámpago del Catatumbo" (Catatumbo lightning) is aunique natural phenomenon in the world. Located on the mouth of the Catatumbo river at Lake Maracaibo (Venezuela), the phenomenon is a cloud-to-cloud lightning that forms a voltage arc more than five kilometre high during 140 to 160 nights a year, 10 hours a night, and as many as 280 times an hour. This almost permanent storm occurs over the marshlands where the Catatumbo River feeds into Lake Maracaibo and it is considered the greatest single generator of ozone in the planet
Moon bows
Moon Bows are extremely rare, and can only be seen at night when the mood is low and either full or almost full.
THE MAELSTROM
A maelstom is basically a very big and powerful whirlpool, a free vortex; a free vortex with quite a downdraft. The original maelstrom was Moskstraumen, which is caused by a very powerful tidal current.
The Fire Rainbow
A fire rainbow is an extremely rare phenomenon that occurs only when the sun is high allowing its light to pass through high-altitude cirrus clouds with a high content of ice crystals.
The Green Ray or green Flash
It is something that happens all be it briefly before a total sunset or sunrise.
Sun Dogs
Sun dogs are atmospheric phenomena of the caused by the refraction of sunlight through ice crystals Such as those hosted in cirrus clouds
Super Cells
Supercell is the name given to a continuously rotating updraft deep within a severe thunderstorm (a mesocyclone) and looks downright scary. They are usually isolated storms, which can last for hours, and sometimes can split in two, with one storm going to the left of the wind and one to the right. They can spout huge amounts of hail, rain and wind and are often responsible for tornados, though they can also occur without tornados
Noctilucent Clouds
Noctilucent clouds are atmospherically high clouds that refract light at dusk when the Sun has already set, illuminating the sky with no seeming light source.
Non-aqueous Rain
its basically when it rains animals instead of water i.e fish, toads, birds etc , its meant to be rare but it does happen. Meteorologists are still unsure of the cause.
Ball Lightning
This is a very rare phenomenon that involves ball-shaped lightning that moves much slower than normal lightning. It has been reported to be as large as eight feet in diameter and can cause great damage.
Fire Whirls
A fire whirl, also known as fire devil or fire tornado, is a rare phenomenon in which a fire, under certain conditions --depending on air temperature and currents--, acquires a vertical vorticity and forms a whirl, or a tornado-like effect of a vertically oriented rotating column of air.
