Which mechanism redirects air masses eastward at approximately 30 degrees latitude within Hadley cells?

💡 Explanation

When rising air in the Hadley cell reaches the upper troposphere, geostrophic balance is established aloft because the Coriolis effect deflects it eastward, leading to the creation of subtropical jet streams. Therefore geostrophic balance causes eastward redirection, rather than adiabatic cooling, buoyancy, or ITCZ convergence which involve vertical or meridional movements.
