Description
Technical Field
The invention belongs to the field of pie-shaped ice drifting accumulation, and particularly relates to an experimental device for simulating pie-shaped ice drifting accumulation on wind-driven waves.
Background
The first stage in sea ice formation is the formation of individual ice crystals at the surface of the ocean. Under the influence of sea waves, the crushed ice crystals coagulate and accumulate to form a cake-like ice resembling a small disk, the diameter of which can reach several meters and the thickness of which can reach 0.4 meter. In the Antarctic region, 50% of the sea ice area consists of cake-like ice floes with a diameter of 2.3-4 meters. Under the action of wind and waves, the cake-shaped ice can drift and accumulate to form large-sized floccules, and the change of the area and the thickness of the polar ice cover can be directly influenced. The accumulation of cake ice can increase the thickness of the ice cover, and the area of the ice cover on the sea surface is relatively reduced, so that the drifting accumulation process plays an important role in the calculation and determination of the area and the thickness of the ice cover of the polar region. Meanwhile, due to seasonal changes, the scale of wind and waves can be changed, so that the research on the change relationship between sea wind, waves and ice covers is very important. However, at present, research on the change relation between the thickness of the ice cover and wind and waves is still lack, so that related experimental equipment is not available, and an experimental device capable of effectively simulating the drifting and accumulation of pie-shaped ice on wind-driven waves does not exist.
