Such a pressure ridge develops in an ice cover as a result of a stress regime established within the plane of the ice. Within sea ice expanses, pressure ridges originate from the interaction between floes, as they collide with each other. Currents and winds are the main driving forces, but the latter is particularly effective when they have a predominant direction.
Pressure ridges in ice cover develop as a result of stress within its plane. In sea ice expanses, these features emerge from the interaction between floes colliding with one another. Currents and winds are the main driving forces, but winds play a particularly crucial role when they have a consistent direction.
