Further work with the Bushby‐Timpson 10‐level model

Abstract

It is interesting to observe that below the critical temperature a constant super-saturation with respect to ice is required both for nucleation on large crystals (Bryant, Hallett and Mason 1959) and also in these experiments. I find this result rather surprising since, if it were simply a question of nucleating new layers, I should have thought a constant vapour pressure would have been more likely than a constant relative humidity.
