La Nina refers to a climate phenomenon where the central and eastern Pacific Ocean experiences cooler-than-average sea surface temperatures

It causes changes in global weather patterns, typically resulting in altered rainfall distribution and temperature variations across different regions

During La Nina, strong trade winds push warm surface water westward, allowing colder water from the deep ocean to rise up along the South American coast

This effect leads to cooler sea surface temperatures in the eastern Pacific

These cooler waters can disrupt atmospheric circulation, leading to changes in rainfall patterns

It often brings wetter conditions to the Pacific Northwest of the United States and drier conditions to parts of Australia

La Nina can influence weather patterns worldwide, affecting regions like South America, Southeast Asia, and parts of Africa, depending on the intensity and duration of the event

La Nina and El Nino are part of the same natural cycle, switching back and forth irregularly over time
