The analysis of stochastic problems sometimes might be easier than that of nonlinear dynamics – at least, we could sometimes guess upon the asymptotic solutions.. Fundamental question: . How (why?) do cloud droplets form in the atmosphere?. Water vapor can supersaturate as “closed” air parcels rise and cool (or cool some other way, e.g. . radiatively. ). Will drops form as soon as relative humidity exceeds 100%?.
