214 C HO is a key ice-growth parameter that determines
215 C the partition between vertical and lateral growth.
216 C The default is 0.5m, increasing this value leads
217 C slower formation of a closed ice cover and thus to
218 C more ice (and thicker) ice, decreasing to faster
219 C formation of a closed ice cover (leads are closing
220 C faster) and thus less (thinner) ice.
