Which outcome results when insolation variability weakens the equatorial temperature gradient?

💡 Explanation

Reduced insolation creates a weaker temperature gradient, therefore diminished thermal wind shear reduces wind speed differences with height, because thermal wind balance relies on the temperature contrasts; rather than amplifying subtropical highs which require pressure gradients.
