Which outcome is directly amplified when a coastal gyre weakens?

💡 Explanation

Increased marine heatwave persistence occurs because reduced gyre circulation impairs heat redistribution, magnifying local warming; therefore, the persistence rises rather than declining as reduced energy disperses less effectively than when gyres are unaffected.
