Natural phenomena



Northern lights, Iceland


The Aurora Borealis, or Australis, (depending on if it occurs in the north or south) is an optical phenomenon which manifests itself in the atmosphere with bright spots, generally red, green or blue. Scientifically, it is caused by the interaction of charged particles (protons and electrons) from the sun with the Earth’s ionosphere. The phenomenon is more intense during periods of high solar activity.


Sort sol, Denmark


During the months of March and April, in the southwestern marshlands of Denmark, you can experience the “sort sol”, which literally means black sun. Sort sol is the event when up to one million birds flock to the skies during sunset and the sun is actually blocked by the birds, hence the name black sun.


Lightning storm, Venezuela


Lightning storms are a beautiful, but also quite scary, atmospheric phenomenon. The bright bolts are triggered when the electrical activity is particularly abundant during a storm. The longest and most intense lightning storm recorded lasted for hours on end and occurred in Los Angeles on July 9,1999. The highest rate of lightning storms was recorded in Venezuela close to the Maracaibo lake  
with 232 lightnings per year.


Moonbow , Zimbabwe


This rare atmospheric phenomenon is not a rainbow, but rather a moonbow, as it is caused by the reflection of moonlight instead of sunlight. The best seasons to experience a moonbow are during autumn and spring. Such moonbows may be seen close to waterfalls like in Yosemite National Park, California. They may also be seen near Corbin, Kentucky or Victoria Falls as well as in Africa on the border between Zambia and Zimbabwe where this picture is from.


Blood rain, India


There have been numerous reportings of blood red rain falling from the sky, but the 2001 spotting in Kerala, India may be one of the most well known. The red rainfall was not an extraterrestrial intervention, as many believed then, instead it was caused by the presence of spores in the air and red algae coming from the ocean.


Pororoca, Brazil


Occasionally with the full moon in February and March, where the Amazon River meets the Atlantic Ocean, you can find waves up to 13 feet high. A very special day for surfers, who can not wait to jump in the river with their boards, but feared by the natives for the dangerous force of the waves. Though there are many theories as to why they’re called pororoca, one of the most popular is that it comes from “poroc-poroc” which in the indigenous language of Tupi means “great destructive noise”.


Luminous water, Thailand


Go on a boat and you will experience something amazing! Glowing water. Is that true? When the sun goes down, take off on a boat into the night and you can see schools of fish glowing greenish-blue in the water. Put your hand in the water and it will make it glow even more. So beautiful. There are several places on earth where plankton lights up the water. Bioluminescent plankton, can you believe that?

Have a great weekend everyone!
