Coupled Atmosphere-Ocean-Sea Ice Floe Model
Atmosphere-Ocean-Sea Ice coupling systems:
Sea ice floe trajectory model: discrete element method (DEM)
Atmosphere model: a two-layer precipitating quasi-geostrophic (PQG) model
Ocean model: a two-layer quasi-geostrophic (QG) model
Dynamics:
Ice floe <-> Ice floe: contact force and torque
Ocean current -> Ice floe: drag forces and torque
Atmosphere wind -> Ice floe: drag forces and torque
Physics:
Ice floe-> Atmosphere: evaporation
Atmosphere -> Ice floe: precipitation
Sun -> Ice floe: radiation
