Scientists at Harvard University conducted computer simulations to find out what the weather was like in the past. They saw that during the warmest climatic eras, droughts were followed by very heavy rains. Such rains covered hundreds of kilometers, and tens of centimeters of precipitation fell within hours. Such rains and periods of drought have alternated.
Also, due to the intense evaporation of moisture from the Earth’s surface, an “inhibiting layer” arose above it. He prevented the rise of water to the height of the formation of rain clouds. The clouds formed higher, but could not reach the ground with rain. As a result, water accumulated in the air, and the temperature until the conditions for the appearance of cloudiness were formed. As a result, all the accumulated moisture fell out in a downpour.
