Fig. 17From: Post-sunset rise of equatorial F layer—or upwelling growth?Plot of the linear growth rate for the interchange instability in the presence of a velocity shear. Curve A (blue) represents the growth rate for the interchange instability. Curve B (red) represents the collisionless KH instability only. Curve C (green) represents the interchange instability modified by presence of velocity shear. Curves have been reproduced from Guzdar et al. (1982, 1983)Back to article page
