The Impacts of El Niño and La Niña on Global Weather Patterns
TLDR The Southern Oscillation weather cycle, which includes the El Niño and La Niña phenomena, can have significant effects on temperatures and rainfall worldwide. El Niño events result in warmer winters in some regions and increased rainfall in others, while La Niña events lead to lower temperatures, droughts, and changes in weather patterns globally.
