← GeographyWhich mechanism intensifies meandering of jet streams within upper troposphere?
A)Latent heat release amplifying Rossby waves✓
B)Planetary albedo increasing thermal gradients
C)Oceanic salinity creating density currents
D)Vegetation transpiration reducing land temperatures
💡 Explanation
When latent heat is abundant (e.g. during thunderstorms), latent heat is released during condensation, which amplifies existing Rossby waves because it strengthens horizontal temperature gradients. Therefore, amplified Rossby waves increases the meandering of jet streams, rather than albedo increase, salinity, or vegetation changes causing this intensification requiring different triggers.
