← GeographyWhich mechanism intensifies meandering patterns in mid-latitude coastal streams during El Niño?
A)Increased glacial runoff destabilizing banks
B)Weakened Coriolis effect on flows
C)Altered jet stream position influencing storms✓
D)Reduced vegetation cover lessening stabilisation
💡 Explanation
During El Niño, altered jet stream positions cause changes in storm tracks and precipitation patterns, because increased storminess and rainfall lead to river discharge fluctuations, intensifying bank erosion and promoting meander development. Therefore altered jet stream positions are primary influencers, rather than runoff, coriolis or vegetation changes which are separate earth systems.
