| Abstract: | It is demonstrated that the magnetospheric convection becomes evident in terms of the AE index only when the power ? of the solar wind-magnetosphere dynamo becomes greater than ～ 1018 erg s?1 or a slightly lower value. An enhanced conductivity is a crucial factor for the magnetospheric convection to manifest even in a low-level increase of the AE index of ～ 50–100 γ. |
