Storm clouds in the Earth's atmosphere is a haven for microscopic life. In the City, has dropped out of this cloud, managed to find several types of bacteria normally live in the plants, as well as several organic compounds contained in the soil. Some types of bacteria can inhabit the small ice crystals in the cloud, which are the cause of rain. Researchers believe that it is the bacteria play a role precipitation.
Chemists from the Danish University of Aarhus have carefully studied the castle - after removal of the outer layer with hailstones and subsequent sterilization, they began to analyze its chemical composition. As a result, hailstones were found thousands of organic and carbon-containing compounds - almost as many as there are in typical rivers. Some bacteria produce a pinkish pigment, allowing them to withstand exposure to UV rays in the atmosphere. Some turned out to be excellent freezing nuclei, whose presence in the atmosphere speeds up the process of cloud formation. If such crystals freeze together in large formations, then fall as rain or snow, depending on the air temperature.
Thus, the bacteria can affect the weather conditions.
It is assumed that the bacteria appear in the cloud using updraft. Based on this we can conclude that the clouds for bacteria - it's a great way to spread around the globe.
