← GeographyWhich outcome occurs when strong temperature gradient appears in the upper troposphere during winter?
A)Intensified polar jet stream forms✓
B)Decreased frequency of La Niña events
C)Weakened Hadley cell circulation develops
D)Increased stratospheric ozone depletion
💡 Explanation
When a strong temperature gradient exists in a polar region, a strong pressure gradient force enhances the Coriolis effect because the temperature difference increases the air density contrast. Therefore, strengthened polar jet stream results, rather than weakened Hadley cell, change in ENSO frequency, or ozone depletion, which depend on different atmospheric or oceanic mechanisms.
