What is an El Niño Event?
Normally, the strong trade winds moving from east to west along the equator push water towards Asia, where it accumulates and heats up. Colder water along the Eastern Pacific rises to replace the water being pushed towards Asia, a process known as upwelling. This cool water provides perfect conditions for productive fisheries along the Eastern Pacific.
🌡️ El Niño is when the Pacific Ocean temperatures are warmer than average, and this weakens the trade winds. These weakened trade winds allow hotter water to flow from the Western Pacific to the Eastern Pacific. This disrupts ocean ecosystems, weather patterns, and increases air temperature throughout the Pacific and North and South America.
📅 El Niño events typically occur every 2-7 years and last between 9 and 12 months. Climate change is increasing the frequency and the severity of El Niño events.
El Niño events negatively impact fisheries throughout the Pacific. Warm water has fewer nutrients for fish and their prey. In turn, this has major economic impacts for many countries and communities. 💰
📈 With El Niño events, we will expect to see stronger heat waves, worsening droughts, increased risk of wildfires, and, with more moisture in the air, we will see more intense floods. 🌧️ Here in Hawai’i, with the warmer ocean temperatures, we expect to see more coral bleaching.
The upcoming El Niño event this summer is predicted to be the strongest on record.
What You Can Do to Prepare:
✅ Prep emergency supplies for storms, droughts, and fires, including water, food, batteries, first aid, and important documents.
✅ Remove invasive vegetation from your yard to reduce fuel for fires.
✅ Plant native plants in your yard to help retain soil moisture. This will also help reduce the risk of fires.
