Two Extremely Rare Nature Events


Fire Whirls


Fire tornadoes are one of the few tornadoes most people don’t get to see a lot; in fact, these are really rare, and the only time when these fire tornadoes would occur is when there's a wildfire or a firestorm. They also form when there's a lot of intense heat and wind which causes the fire to rise up.


Fire twisters can be up to 10–50 m (33–164 ft) tall and a few meters wide, and they can last up to a few minutes. Some fire tornadoes can be more than 1 km (0.6 mi) tall and have wind speeds over 200 km/h (120 mph) lasting for more than 20 minutes.

One of the most extreme examples of a fire whirl is the one that happened back in 1923 in Japan. It occurred during the Great Kantō earthquake, along with a tsunami. Click here to get more information about this historic event.



 

Multi-Colored Snow


According to ThoughtCo, there can be many different colors of snow, including red, green, blue, yellow, brown, black, and gray snow.


The reason why there is “watermelon snow’’ (photo below) is because of the growth of algae. One type of algae is Chlamydomonas Nivalis, which is associated with red or green snow, also known as watermelon snow. Watermelon snow is the most common in polar regions. This algae also contains photosynthetic chlorophyll, which makes it green, and the secondary red is carotenoid pigment.


Orange and brown snow are caused by dust, sand, or the pollution that's in the air.


Gray or black snow is caused by precipitation through soot, which is tiny particles of fossil fuel which also may cause the snow to be oily and smelly. This type of snow is only commonly seen in the early snowfall at a really bad polluted area, a recent spill, or accident.


Blue snow can be seen it a shadowed location, which is caused by huge amounts of frozen water that is shown as pale blue.
