摘要：

The solar–terrestrial system consists of many neighboring physical regions, which include the photosphere, solar corona, solar wind, magnetosphere, ionosphere, atmosphere, lithosphere and interstellar medium. The electrodynamic coupling among neighboring regions leads to the generation of many observed natural phenomena. The followingimportant electrodynamic coupling processes will be presented and reviewed in this talk. (a)The plasma shear flows in the solar photosphere lead to the formation and eruption of solar prominences. (b)The coupling between solar wind and magnetosphere through magnetic reconnection and kinetic Alfvén waves (KAWs) leads to the transport of particles and energy from the solar wind to magnetosphere.(c)The micro-scale processes provide electric resistivity for magnetic reconnection and ion heating for shock formation in collisionless plasma. (d) The electric coupling among lithosphere, atmosphere and ionosphere may lead to total electron content (TEC)variations and formation of nighttimeplasma bubbles in the ionosphere. (e) The coupling of heliosphere to the interstellar medium leads to the formation of termination shock, heliosheath and heliopause as observed by Voyager 1 and 2.
