El Nino is coming. We need to know about it. First, we learn about trade winds. They blow from east to west around the world. In the Pacific Ocean, they help move warm water to Asia and Australia. Then, cold water comes up to South America.
Every two to seven years, something changes. The winds get weaker or change direction. The warm water goes back to the eastern Pacific. If the sea surface temperature changes by more than 0.5° C, it's called an El Nino event. El Nino brings warm water and heavy rain to South America. Asia and Australia get more droughts. The Earth is getting warmer, and El Nino makes it worse. This is bad for marine life and the ocean's ability to absorb CO2.
We need to watch El Nino. It can hurt the planet. We should learn about atmospheric pressure, ocean surface temperature, and climate change. These things are important for our planet. We must take care of the Earth and its ecosystem. We should also know about subsurface water and how it affects the ocean. By understanding these things, we can help keep the Earth safe.
