N2 - We study average characteristics of plasma sheet convection in the middle tail during different magnetospheric states (Steady Magnetospheric Convection, SMC, and substorms) using simultaneous magnetotail (Geotail, 15-35 RE downtail) and solar wind (Wind spacecraft) observations during 3.5 years. (1) Large data set allowed obtain the average values of the plasma sheet magnetic flux transfer rate (Ey) and directly compare it with the dayside transfer rate (Emod) for different magnetospheric states. The results confirm the magnetic flux imbalance model suggested by Russell and McPherron (1973), namely: during SMC periods the day-to-night flux transport rate equals the global Earthward plasma sheet convection, during the substorm growth phase the plasma sheet convection is suppressed on the average by 40%, whereas during substorm expansion phase it twice exceeds the day–to-night global flux transfer rate. (2) Different types of substorms were revealed. About 1/3 of all substorms considered displayed very weak gro
