← GeographyWhich mechanism amplifies the northward swing of the meandering jet stream transporting water vapor across continents?
A)Orographic lift from coastal ranges focusing rainfall
B)Latent heat release causing upper-level divergence✓
C)Radiative cooling creating continental high pressure
D)Ekman transport drawing surface waters convergently
💡 Explanation
When a meandering jet stream sweeps warm moist air over land, latent heat release from condensation drives upper-level divergence via ascent, strengthening anticyclonic ridges downstream that further intensify the northward sweep. Therefore, latent heat release results, rather than options which have weak air current interactions.
