AB - The key dynamics of the magnetotail have beenresearched for decades and have been associated with eitherthree-dimensional (3-D) plasma instabilities and/or magneticreconnection. We apply a global hybrid-Vlasov code, Vlasiator, to simulate reconnection self-consistently in the ion kinetic scales in the noon–midnight meridional plane, including both dayside and nightside reconnection regions withinthe same simulation box. Our simulation represents a numerical experiment, which turns off the 3-D instabilities butmodels ion-scale reconnection physically accurately in 2-D.We demonstrate that many known tail dynamics are presentin the simulation without a full description of 3-D instabilities or without the detailed description of the electrons. Whilemultiple reconnection sites can coexist in the plasma sheet,one reconnection point can start a global reconfiguration process, in which magnetic field lines become detached and aplasmoid is released. As the simulation run features temporally steady solar wind input, this global reconfiguration isnot associated with sudden changes in the solar wind. Further, we show that lobe density variations originating fromdayside reconnection may play an important role in stabilising tail reconnection.
