Which change to atmospheric conditions leads to Hadley cell expansion at lower latitudes?

💡 Explanation

When global average surface temperature increases, stronger thermal gradients drive more vigorous atmospheric convection, causing the Hadley cells to expand towards the poles. Therefore Hadley cell expansion is triggered, rather than ozone depletion, evaporation rate decrease or albedo decrease which impact stratospheric processes or energy absorption at upper latitudes.
