← GeographyWhich atmospheric effect causes an elongated wave pattern in upper-level winds?
A)Hadley cell thermal circulation
B)Coriolis force on synoptic flows✓
C)Orographic lifting over landmasses
D)Latent heat release from convection
💡 Explanation
When large-scale air masses move poleward or equatorward, the Coriolis force causes deflection due to Earth's rotation, resulting in undulating Rossby waves. Therefore, Coriolis force impact results, rather than Hadley cells, orographic lifting, or latent heat, which relate to air mass heat and moisture.
