The ocean is a very sensitive system, according to Rignot, and even small shifts, like changes in ocean circulationdriven by wind, can make a huge difference in ice shelf melt.
In lake, wind-driven velocities are slow, wind power has an obvious impact on circulation structures, changes of wind power immediately brings changes of flow field.
The combined surface currents flow northwestward flow, while the bottom compensation currents flow southeastward. The combined circulation is mainly driven by the wind.
