Introduction

[2]  Now it becomes more and more evident that the nucleation bursts can contribute substantially to CCN production and can thus affect the climate and the weather conditions on our planet. Commonly accepted opinion connects the nucleation bursts with an additional production of nonvolatile substances in the atmosphere that can then nucleate and/or condense on newly born particles, foreign aerosols, or atmospheric ions. The production of nonvolatile substances, in turn, demands some special conditions to be fulfilled imposed on the emission rates of volatile organics from vegetation, current chemical content of the atmosphere, rates of stirring and exchange processes between lower and upper atmospheric layers, presence of foreign aerosols (submicron fraction, first of all) serving as the condensational sinks for trace gases and the coagulation sinks for the particles of nucleation mode, the interactions with air masses from contaminated or clean regions. Such a plethora of very diverse factors most of which have a stochastic nature prevents direct attacks of this effect. A theoretical modelling of the nucleation bursts is thus of primary importance.
