Cause heavy rains called aerosols Facts
Elevated airborne levels of aerosols — particulate soot, dust and sulphates — has led to increase rainfall in some regions of the world. A closer look at this phenomenon will allow scientists to more accurately predict the level of rainfall and other climatic changes.
Release of aerosols into the atmosphere during the combustion of coal or gas, the industrial and agricultural activities, forest fires, which leads to environmental problems such as air pollution, and the negative impact on human health.
Israel's Weizmann Institute scientists believe that the relationship between the level of aerosols in air and precipitation observed both on land and in the ocean, as in the tropics, subtropics and temperate latitudes in all continents. Strong rains provoked extensive emissions of sulfur dioxide during volcanic eruptions. Once in the atmosphere, the sulfur particles accumulate in the rain clouds and becomes the center around which water droplets form and ice. The higher the concentration of sulfur dioxide in the cloud, the more abundant and frequent rainfall will.
It is suggested that the large clusters of clouds may be involved in the process of cooling the Earth's surface, reflecting the sun's radiation and directing it back into space. It was also found that the increased concentration of aerosols leads to an increase in the maximum height of the clouds.
