Which phenomenon's intensity influences the latitudinal extent of the Hadley cell circulation pattern?

💡 Explanation

When tropospheric water vapor increases, the greenhouse effect intensifies because it absorbs and re-emits longwave radiation, increasing surface temperature and strengthening convection in the tropics, expanding the Hadley cell. Therefore the water vapor greenhouse effect primarily governs Hadley cell extent, rather than other radiative or shielding phenomena.
