La Niña
Tropical cyclone (typhoon or hurricane)
Intense circular storm that originates over warm tropical oceans and is characterized by low atmospheric pressure, high winds, and heavy rain

Flood
High-water stage in which water overflows its natural or artificial banks onto normally dry land
Main types of floods
Inland flooding
Flash floods
River flooding
Coastal flooding
Urban flooding
Storm surge
Irregular sea-level rise during tropical cyclone where powerful winds force the ocean water over the coastal low-lying areas, leading to flooding
El Niño
Large-scale ocean-atmosphere climate interaction linked to a periodic warming in sea surface temperatures across the central and east-central Equatorial Pacific
La Niña
Periods of below-average sea surface temperatures across the east-central Equatorial Pacific
El Niño effects
Diseases related to water scarcity or shortage, red tide blooms, disorders associated with high temperatures
La Niña effects
Diseases related to contaminated water due to flooding, diseases brought by mosquitoes, accidents and injuries
