In scenes remembering an alien invasion film, giant clouds gathered above Buenos Aires, Argentina and Medellin, Colombia on February 22.
Did atomic bombs just exploded in those south american metropoles?Both cities were hit by severe thunderstorms that left thousands without power.
Independence Day cloud in Buenos Aires, Argentina on February 22, 2017
A huge circular cloud exactly like the one signalling the end of the world in the film Independence Day has stunned people in Argentina.
The impressive cloud was seen moving over Buenos Aires, like in the Hollywood blockbuster.
Shocked witnesses filmed the weather phenomenon on their phones, calling it the new ‘Independence Day’ due to its similarity with the spaceship in the 1996 movie.
These kinds of cumulus cloud are anvil clouds. These cumulonimbus clouds have reached the level of stratospheric stability and have formed the characteristic flat, anvil-top shape.
A cumulonimbus incus means that the thunderstorm is in its mature stage and thus, it can produce many dangerous elements like bursts of cloud to ground lightning, hailstones, torrential rains, strong winds and in some cases tornadoes.
Downburst in Medellin, Colombia on February 21, 2017
Have you ever seen a downburst like that? Probably not! But whatch the pictures below and let me a note afterwards.
Downbursts are rapidly descending downdrafts of air, found below clouds that have precipitation (rain and hail). The downbursts form when falling raindrops pass through drier air en route to the ground.
When the downdraft hits the ground, it spreads out rapidly in all directions and becomes known as a downburst.
These fast downdrafts of air from thunderstorms are called downbursts, and can be 1 to 10 km in diameter. Downburst wind speeds have been known to exceed 100 mph.
This most probably was a so-called microburst, meaning that the damaging winds are confined to an area less than two and a half miles across. Otherwise, it’s a macroburst.
Such creepy sky phenomena! WOW!
