In-Depth Analysis
La Niña's Influence on Weather
La Niña is part of the El Niño-Southern Oscillation (ENSO) cycle, which includes El Niño (warmer waters) and ENSO-Neutral phases. La Niña's cooler waters can alter jet stream patterns, affecting temperature and precipitation across different regions.
