← GeographyWhich increased occurrence accompanies divergence in upper-level air streams?
A)Intense surface cyclone formation initiation✓
B)Stable atmospheric temperature inversions
C)Widespread decrease in surface pressure
D)Strengthening of the polar jet stream
💡 Explanation
Surface cyclone formation initiates because increased upper-level divergence causes air to rise via mass continuity in the lower atmosphere; therefore, this favors cyclogenesis due to reduced surface pressure, rather than suppressing it as stable inversions would.
