  This paper investigates the influence of Earth's dipole tilt angle on the
reverse convection cells (sometimes referred to as lobe cells) in the Northern
Hemisphere ionosphere during northward IMF, which we relate to high-latitude
reconnection. Super Dual Auroral Radar Network plasma drift observations in
2010-2016 are used to quantify the ionospheric convection. A novel technique
based on Spherical Elementary Convection Systems (SECS) that was presented in
our companion paper (Reistad et al., 2019,
https://doi.org/10.1029/2019JA026634) is used to isolate and quantify the
reverse convection cells. We find that the dipole tilt angle has a linear
influence on the reverse cell potential. In the Northern Hemisphere the reverse
cell potential is typically two times higher in summer than in winter. This
change is interpreted as the change in interplanetary magnetic field-lobe
reconnection rate due to the orientation of the dipole tilt. Hence, the dipole
tilt influence on reverse ionospheric convection can be a significant
modification of the more known influence from v(O$_{sw}$)B(O$_{z}$). These
results could be adopted by the scientific community as key input parameters
for lobe reconnection coupling functions.
