Which effect increases flooding risk when La Niña recurs?

💡 Explanation

Intensified trade winds cause increased moisture transport, enhancing precipitation events because the Walker circulation pattern amplifies the existing convective activity; therefore, increased flood risk stems from more frequent, intense rainfall rather than divergence or thermocline disruption.
