As Villefand noted, at present the sun is “as energetically saturated as possible”. This is due to the fact that it is located at a minimum height from the Earth.
“After all, now is the period of the summer solstice, which will last another ten days. The air is dry now: there is no dust, because it has already settled, and there is no moisture either. In conditions where there are few clouds, the ultraviolet (UV) index is large, ”he explained.
According to him, a very high and high level of the UV index will be recorded in the North Caucasus and Southern Federal Districts, a high level of the UV index will be in most regions of the Central Federal District. Also, high and very high levels of UV index will be in the south of Siberia.
Earlier, Wilfand predicted a heterogeneous summer in Russia.
