Which phenomenon results when upper-level divergence aloft exceeds surface convergence in an idealized Hadley cell?

💡 Explanation

When upper-level divergence surpasses surface convergence, mass accumulates aloft because the outflow exceeds the inflow, causing increased atmospheric pressure, resulting in subsidence. Therefore intensified subtropical high pressure develops, rather than trade wind weakening, increased thunderstorm frequency, or ITCZ shift which depends on uneven heating and other complex factors.
