Mesoscale nowcasting of sea ice movement through the Bering Strait with a description of major driving forces.

Abstract

Surface atmospheric pressure data from a triangular station network surrounding the Bering Strait are used to calculate hypothetical geostrophic wind velocities. Net daily Strait sea ice movement is derived from visible and infrared NOAA satellite imagery for November through May, 1974 to 1084. These historical ice- motion data and network wind-velocity data are used to develop an empirical 12h advance forecast (nowcast) sea ice movement model with all-weather capabilities.-from Authors
