In the middle of 2022, over Sioux Falls, South Dakota, America. Suddenly, the sky turned green as if it had been hit by a magic laser.
What is happening is a rare natural phenomenon caused by the refraction of light hitting the ice. (or hail) accumulated in the clouds It appears green, explains Scientific American
First of all: Storms usually happen in the afternoon and evening. The sunlight will have a reddish-yellow shade. – Second: During this time, the water in the clouds reflects blue especially well. – Third: When the two elements come together, they appear green, as see
“This is usually a visible sign that a thunderstorm has the potential to make very large hail,” Martin said.
for the phenomenon over South Dakota, It is the formation of “Hurricane Derecho”, a thunderstorm, fast-moving Its destructive radius is similar to that of a tornado, its winds exceed 93-160 km/h and can travel hundreds of kilometers. Can cause enormous damage across up to 5 states
the fun fact
“OceanTherm” company from Norway is developing technology to stop hurricanes by lowering ocean temperatures with “bubble curtains,” meaning they activate bubbles to draw water from the bottom of the sea. (with low temperature) to the surface (with high temperature)
This is because hurricanes are caused by high-temperature sea water that evaporates – joins with moist air – condenses to form rain clouds. It is a factor that can help reduce the occurrence of hurricanes.
