La Nina

According to the Bureau of Metrology, Australia, there are early signs that a La Nina weather pattern may form in the Pacific Ocean later this year.

Key Highlights

• It is a climate pattern that describes the cooling of surface-ocean water along the tropical west coast of South America.
• La Niña is a weather phenomenon that occurs in the Pacific Ocean. 
• It is the reverse phenomenon of El Niño, and both are part of the larger El Niño-Southern Oscillation (ENSO) cycle. 
• The trade winds become stronger than usual, pushing more warmer waters towards the Indonesian coast, and making the eastern Pacific Ocean colder than normal.
• La Nina means Little Girl in Spanish. La Niña is also sometimes called El Viejo, anti-El Niño, or simply “a cold event.”
• La Nina typically enhances the monsoon rainfall in India.
