← GeographyWhich outcome occurs when thermal gradients accentuate the Coriolis effect?
A)Increased polar jet stream meandering✓
B)Weakening of trade wind patterns
C)Expansion of subtropical high pressure
D)Formation of intense tropical cyclones
💡 Explanation
Increased thermal gradients enhance the Coriolis effect, amplifying the Rossby wave patterns and leading to increased jet stream meandering, because this increases upper-level divergence. Therefore, meandering increases, rather than weakened trade winds, caused by other circulation variations.
