Abstract : One facet of weather modification is the dissipation of a warm fog or the improvement of visibility within it by means of seeding with condensation nuclei. The analysis of the effectiveness of this type of nuclei finds its roots in the mathematical expression for condensational growth - one of the few fundamental equations in cloud physics which has, only during the past twenty years, been recognized as a distinct branch of physical meteorology and, more recently, as an integral part of atmospheric physics. Being a young science, cloud physics has embodied areas of study which are in need of better understanding and further development, one such area being the processes of condensation and precipitation. The fundamental equation is applicable to the growth of an isolated and immobile saturated solution droplet in a stationary medium of moist air. It is the purpose of this paper to examine this equation critically from a theoretical point of view. (Author)
