Clearing the atmosphere from gaseous pollution and aerosols occurs due to the water cycle. As a rule, water in the atmosphere is represented in three aggregation states: gas, liquid and solid. Recently, increased attention is focused on clusters which are formed due to hydrogen bonding. Clusters, especially aggregates of small size, can be considered as a special state of substance. Water vapor as the main representative of water in the atmosphere contributes significantly to its clearing. Clusters are formed from water vapor and subsequently they form water drops or snowflakes which fall as precipitation. At their forming stage and during their subsequent presence in the atmosphere, both clusters and larger formations absorb molecules of pollution substances. ... Читать дальше »
