Ice Breeze Mechanism for an Ice Divergence-Convergence Criterion in the Marginal Ice Zone.

摘要

A coupled air-ice-ocean theoretical model for the marginal ice zone (MIZ) is developed and used to show that an off-ice and divergent wind field not only produces a dilation of the MIZ (as is generally thought), but also generates a compaction of MIZ for some circumstances. An ice divergence- convergence criterion in the MIZ is found and used to help explain some features, such as ice edge bands, and the formation and maintenance of polynyas and leads.
