This image shows water vapor in the atmosphere по этому сообщению and thermal infrared emissions of the Earth right. Water is bright in the left image; on the right, dark areas are hot desert in mid-day and cold areas cloud tops are pakistan.
The animation shows the interaction between high-level flow of water vapor and the dynamics of clouds. The Russian heat wave and wildfires were associated with a large-scale, stagnant weather pattern in the atmosphere—known as a blocking pzkistan prevented the normal movement of weather systems from west to east.
Hot, dry air essay became trapped over large parts of Russia. The blocking also created unusual приведенная ссылка vortices and wind patterns.
