El Nino is a weather phenomenon that occurs every few years in the Pacific Ocean.
This winter's El Nino is projected to be strong, meaning it will have a significant impact on global weather patterns.
The strength of El Nino is determined by the temperature of the ocean water in the Pacific.
A strong El Nino can cause droughts in some areas and heavy rainfall in others.
The last strong El Nino occurred in 2015-2016 and caused severe weather events around the world.
Scientists and meteorologists are closely monitoring the current El Nino to better understand its potential impact.
It is important for individuals and governments to prepare for the potential effects of a strong El Nino.
