On the exponential decay of spray flux in the marine environment
A simple numerical model is developed to calculate the horizontal spray density distribution and the time evolution of the vertical distribution of the liquid water content for two spray clouds with different drop-size spectra -- a Marshall-Palmer and a log-normal spectrum. The algorithm developed b...
