THE ROLE OF THE ATMOSPHERIC COMPONENTS IN CONDENSATION NUCLEI FORMATION

N. N. Morar

An attempt is made to understand the role of the atmospheric components of a natural and anthropogenic origin in the formation of condensation nuclei (micelles) in the southern Archangelsk region using a quantitative chemical analysis of some ingredients of fresh snow. The micelle nuclei principally consist of chlorides and metal oxides and also other salts. In most of the samples studied, the charged particles, i.e., ions, are adsorbed by micelle nuclei by layers as potential-determining chloride, nitrite, nitrate, and hydrocarbonate ions, and also as counterions NH+4, H3O+, and others, forming a double electric layer on the periphery of which the water vapor condenses and crystallizes, i.e., snowflakes form.
