The surface of the ocean warms and cools intermittently as it interacts with the strength of the trade winds, which blow from east to west in normal conditions. As the ocean surface temperature changes in response to atmospheric conditions, it modifies rainfall patterns. It’s a bit of a scientific dance between ocean and atmosphere, with the opposi...
When warm water builds up along the central and eastern tropical Pacific Ocean, an El Niño occurs. This increases moisture rising in the air, resulting in more rainstorms. In the US, winter temperatures tend to be warmer than normal in the Northwest with decreased rainfall, while the Southeast experiences wetter-than-average conditions. For example...
Conversely, when cool water builds up along the same region, a La Niña occurs with the opposite impact. In the US, winter temperatures tend to be cooler than average in the Northwest and warmer than average in the Southeast. In 1988, the unusually cool water caused the atmosphere to cool in response. As less water evaporated, the air became dryer, ...
Together, El Niño and La Niña are part of a natural cycle that can significantly impact not only global weather, climate, and ocean conditions but also food production, human health, and water supply. These systems typically last about one to two years, with the cycle alternating every three to seven years. As we near the tail-end of multiple El Ni...

El Niño and La Niña episodes typically last nine to 12 months, but some prolonged events may last for years. In Spanish, El Niño means The Little Boy, or Christ Child, and La Niña means The Little Girl. While their frequency can be quite irregular, El Niño and La Niña events occur on average every two to seven years.
