Numerical Calculation Model of Sea Freezing in Fishing Port During Winter Season

摘要

We developed a multipurpose freezing simulation model that can be used as a tool to provide a relatively evaluation of proposed countermeasures against port freezing during winter season and examined its application to a field site. This freezing simulation consists of three submodels: i) Seawater flow field calculation; ii) Phase changes in ice or snow; iii) Movement of ice floes. The phase changes in ice and snow is able to take a variety of meteorological conditions and stages of melting into consideration. We confirmed that this simulation method could roughly reproduce freezing tendencies and characteristics from the comparisons between observed and calculated results.
