After the atmospheric phenomenon, rainfall of about 10 cm thick and fierce gusts of wind were recorded in the city.

This type of case is known as “Derecho”, and it is a wind storm that generally coincides with thunderstorms, and normally extends for hundreds of kilometers.
They argue that large, thick storm clouds directly impact the way we perceive the color of the sky, which explains why the eye perceives it as green.
“When this tuning light is transmitted by a massively thick cloud made up of water droplets and ice particles, the results are a green sky,” Bohren said.
The professor compared the phenomenon to putting a glass of water with a drop of yellow food coloring behind a glass of water with blue food coloring to produce the same tint of green that transmits light in the sky.
