Storm clouds contribute to global warming: study.

Грозовые облака способствуют глобальному потеплению: исследование
According to Pacific National Laboratory, U.S. Department of Energy, storms can make a significant contribution to global warming, due to their ability to capture and retain warm air. So maybe in the future, environmental scientists have to radically adjust their climate models in the light of recent research.As explained in a recent report from the representative of the Department of Energy Jiva fan, warm air helps to seal storm clouds, causing them to "peak" to climb into the upper atmosphere and capture more heat, especially at night. According to him, global climate models do not account for this effect, since in them the process of formation of storm clouds presented enough detail.
The storm clouds, which are also known as deep convective clouds, are an important part of the climatic cycle. Due to their size, they represent a large portion of solar radiation back into space. However, a recent study showed that with the warm air and the storm clouds are sucking dirt particles in it. These particles inhibit the formation of large raindrops in the cloud, and as a consequence, the "return" of water on the ground as rain.This in turn leads to a further increase in the storm clouds that absorb more water vapor, which is, as scientists believe, a major factor in regional weather systems.

The researchers looked at two different types of storm systems - the warm summer thunderstorms in the southeast of China and the cool windy frontal systems on the Great Plains of Oklahoma. Simulated on a computer, "the storm", scientists have studied in detail how to develop cloud conditions change, such as wind speed and air pollution.They found that air pollution leads to increased summer thunderstorms until a severe storm, which is evidence of a warming effect. The researchers also noted that air pollution causes increased absorption of heat by storm clouds.According to Fan, the research findings are very important for modeling global warming, but they are calculated only on a particular day - when there are thunderstorms.
