Figures

Grahic Jump Location
A cylinder exposed to vertically falling freezing rain: a) Schematic representation and definition of variables; b) Cumulative impinging (dashed, first term on RHS of Eq. (2)) and freezing (solid, second term on RHS of Eq. (2)) mass fluxes as a function of azimuth for three values of the runback factor, S (see Eq. (3)).
Grahic Jump Location
Azimuth of the right half-accretion center of mass as a function of the runback factor. The solid curve corresponds to the analytical model, Eqs. (8) and (10), while the points are predictions of the morphogenetic model. The four figures depict the ice accretion shape for various values of S.
Grahic Jump Location
The influence of the runback factor on the ice accretion shape as predicted by the morphogenetic model. Five consecutive ice layers formed during successive 10 mm precipitation intervals are depicted. The empty squares represent the cylinder surface. The cylinder diameter is 35 mm and the total precipitation is 50 mm. a) S=1;b) S=1/2π;c) S=3/4π;d) S=π.
Grahic Jump Location
The influence of the runback factor, S, and the total precipitation, p, on the ice accretion, as predicted by the morphogenetic model: a) Ice load (kg m−1 ); b) Ice accretion radial equivalent thickness (mm); c) The center of mass of the right-hand half of the accretion, for the values of S listed in the legend. The center of mass moves away from the cylinder center with increasing precipitation: 10, 20, 30, 40, and 50 mm.
