Afforestation creates rain
Updated: Dec 1, 2022
The volume of water entering the World Ocean from all the rivers on earth is about forty-three thousand cubic kilometers. This is water that evaporates into clouds and is carried across the sky to the continents. However, rain clouds, approaching the earth, cannot go far without stopping. For clouds to move further on land, sufficient water evaporation is required to create new clouds. So clouds cover most of the continents and create new rains.
When not enough water evaporates to create clouds, the amount of rain decreases. When there is not enough rain to fill the rivers, the rivers dry up. When the rivers dry up, the area turns into a desert. And it is the forest, like giant natural pumps that evaporate water, that ensures the delivery of even greater volumes of moisture from the ocean to remote corners of the land.
The desert is almost always closed to the appearance of rains. The wind there most of the time blows towards the sea, due to the fact that evaporation over the ocean is greater than over the desert. When it rains over the desert, some of the water quickly flows into the sea and the rest of the water dries up, not lingering on bare soil. Short-term evaporation is not able to attract additional sea air to create new rain. Desertification is a process that is created much faster than reforestation in hot areas.
The forest, unlike the desert, increases the amount of rain. The water vapor that has evaporated from the leaf surfaces condenses in the upper cold layers of the atmosphere, which causes the air above the forest to be diluted, which creates upward air flows over the forest, sucking in moist air masses from the ocean and bringing them to dry land.After precipitation, dry air returns to the ocean through the upper atmosphere.This process is extended over time due to the fact that the forest soil is saturated with moisture, not allowing water to drain quickly into the sea or evaporate.And long-term strong evaporation forms new rains.
During afforestation, most of the rain begins to form over the mainland as a result of the constant evaporation of water from trees and the formation of clouds.
Only a third of the precipitation on the continents comes from evaporation from the ocean. And if the ocean moisture did not pour out onto the land, just as rain and snow did not fall, all glaciers and swamps, lakes and rivers would completely dry up in less than ten years.
