Abstract
The influence of magnetic shear on the current convective instability is investigated for conditions typical of the high‐latitude F region during the diffuse aurora. It is found that magnetic shear (1) reduces the growth rate of the instability (although it does not stabilize the mode) and (2) substantially localizes the mode structure parallel to the density gradient.Keywords
