Record #176349:

A coupled coastal polynya-atmospheric boundary layer model / I.A. Walkington, A.J. Willmott.

Title: A coupled coastal polynya-atmospheric boundary layer model / I.A. Walkington, A.J. Willmott.
Author(s): Walkington, I. A.
Willmott, A. J.
Date: 2006.
In: Journal of Physical Oceanography. (2006.), Vol. 36(5) (2006)
Abstract: Presents opening solutions of one-dimensional coastal polynya flux model in which frazil ice is characterised by depth and concentration. In comparison with polynya flux models in which variable frazil ice concentration is absent, model predicts smaller heat flux to atmosphere. Model exhibits wider steady-state polynya and longer opening times compared with models in which ice concentration is neglected. When coupled to lower-atmosphere boundary layer model, model demonstrates that polynya opening time and steady-state width are significantly altered in coupled, as compared with decoupled, system.
