← GeographyWhich outcome occurs when strong temperature gradients develop across the Gulf Stream?
A)Intensified mid-latitude cyclone formation✓
B)Weakening of the thermohaline circulation
C)Increased coastal upwelling intensity
D)Reduced sea ice extent at poles
💡 Explanation
Strong temperature gradients over the Gulf Stream cause baroclinic instability, which enhances cyclone formation because this is a fundamental atmospheric response to temperature imbalances. Therefore, intensified mid-latitude cyclone formation occurs, rather than directly influencing thermohaline circulation or sea ice.
