Which risk increases for coastal communities when the subtropical jet stream meanders southward during winter?

💡 Explanation

Anomalous southern meanders increase storm surge vulnerability; because the jet stream guides storm tracks via steering, therefore intense storms impact coastlines, causing Coastal Erosion vulnerability, rather than increased upwelling triggered by other mechanisms.
