1. Normal Times
Trade winds usually blow from east to west. Warm surface water piles up near Indonesia and the Philippines.
👋 Welcome!
Hi! This website explains some of the ideas in the EARTH SIGNAL YouTube video “The Pacific Is Building Toward a Record El Niño — What Happens Next Will Be SHOCKING.”
El Niño is a natural climate pattern in the tropical Pacific Ocean. It can change weather in many places around the world.
