According to him, the essence of an unusual climatic phenomenon lies in the difference between the temperature in individual neighboring regions.
“On Wednesday, a completely non-standard situation is when it is still hot in Moscow, +26 ... + 28 ° С, in the east of the Moscow Region - up to +33 ° С, and in the west - from +18 ° С to +23 ° С. This is really unusual. There will be such a large temperature gradient, ”TASS quoted him.
He also noted that the “temperature gradient” in the metropolitan area will be associated with the movement of the cold frontal section from the west.
