← GeographyWhich mechanism diminishes latent heat transport from tropical streams towards temperate latitudes?
A)Increased coastal cloud albedo
B)Orographic rainfall reduction
C)Enhanced subtropical jet blocking
D)Reduced evapotranspiration efficiency✓
💡 Explanation
When evapotranspiration efficiency is reduced, the latent heat flux diminishes because less water vapor is transported into the atmosphere, decreasing poleward energy transfer. Therefore reduced evapotranspiration limits transport, rather than cloud albedo, orographic effects, or jet stream changes all of which have different geographic and atmospheric drivers.
