Which outcome exacerbates coastal flooding during an El Niño event due to altered atmospheric circulation?

💡 Explanation

When an El Niño occurs, weakened trade winds shift warm water eastward, promoting increased low-pressure systems because atmospheric instability favors cyclogenesis, leading to intense storms and higher sea levels. Therefore increased low-pressure frequency amplifies coastal flooding, rather than changes inland, or altered thermocline dynamics which cause different effects.
