ERT3 meteorologist Sakis Arnautoglu explained a strange natural phenomenon, captured and posted on the Internet by users who saw it with their own eyes.
The Carmel Weather Front officially brought winter to Greece and snow fell in many areas. The population of the country, rejoicing that “nature has dressed in white”, went out for a walk and frolic in the fresh air. At the same time, some fans of taking pictures were surprised to find that the snow is somehow strangely “twisted in a spiral” (and, moreover, it moves!), Which was very interesting and prompted to develop various theories.
Meteorologist Sakis Arnautoglu in his post on Facebook hastened to explain the natural phenomenon in order to prevent speculation and rumors (for example, alien origin, etc.). What we see in the photo are snow globes that are formed by the wind. In order for the snowballs (“tumbleweeds” – mini-drifts) to set in motion, the wind must be sufficient, but not very strong, the temperature of the upper layer of snow must be slightly above zero (melt), and the lower layers must be “light and fluffy “, but with a temperature of minus.
Under these conditions, the snow can be partially deformed by the wind, and therefore we can observe this weather phenomenon.
