The driving mechanism of characteristic ion flow in plasma hole is examined from the viewpoint of force balance in the fluid equation. On the one hand, the balance between electric force and Lorentz force determines the flow velocity field in peripheral region, which gives rise to E x B rotation of the peripheral plasma. On the other hand, it is revealed that the balance between centrifugal force and Lorentz force governs the flow velocity field in central region, i.e., anomalous E x B solution is realized in central region. A remarkable similarity between the flow field of typhoon and the plasma hole is pointed out. The effective viscosity of the plasma hole is evaluated by its vorticity distribution. It is revealed that the plasma hole exhibits anomalous viscosity, the value of which is three orders of magnitude higher than the classical one. The characteristic radial flow observed in the plasma hole is attributable to its anomalous viscosity.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
