How La Niña will bring changes to the world's weather patterns

Developing ocean-atmospheric phenomenon will influence our weather in the coming months

There is a phenomenon developing in the Pacific Ocean that will be the cause of many weather events over the coming months. Its name: La Nina.

La Nina is an ocean-atmospheric coupled phenomenon occurring every few years where sea surface temperatures in the eastern tropical Pacific Ocean are below normal. Stronger than normal trade winds across the central Pacific advect warmer sea surface temperatures into the far west Pacific towards Indonesia. This encourages strong upwelling of the typically colder waters along the west coast of South America, later extending into the central Pacific.
