Most people know the phenomenon of El Niño. However, La niña it also has a problematic effect for people and is not as well known to the public.

La Niña is a climatic phenomenon that, like El Niño, belongs to a part of the natural cycle of climate in the world. The Child is also called Southern Oscillation. This cycle has two phases: the warm phase when we have El Niño and the cold phase when we have La Niña. But how are they different?

When the trade winds They blow strongly from the west, the temperatures of the equator and its surroundings decrease, so the cold phase called La Niña begins. And on the contrary, when the intensity of the trade winds is weaker, the surface temperatures of the sea increase and the warm phase called El Niño begins.

These phenomena cause changes in the rain regimes of all tropical regions for several months and these changes alternate in periods that can vary between five and seven years.

La Niña had devastating effects in different areas of the world in 2015 and the first months of 2016. However, according to the World Meteorological Organization (WMO) this phenomenon will be more neutral or weak in the coming months. It has been reported that there are between 50% and 65% chance La Niña is weak during the last three months of 2016 and the first three months of 2017.

This is very good news after the events of the El Niño phenomenon last year and at the beginning of this year. Has been The most intense Niño ever recorded and that is why the highest temperatures have been recorded globally. These meteorological phenomena are opposite phases of the interaction between the atmosphere and the Pacific Ocean, which is why they cause opposite effects on the climate in different parts of the world.

      Well, actually, although several studies have been carried out on the subject, and some have managed to statistically link the increase in rainfall in some communities with the phenomenon, the conclusions do not have the desired weight. Therefore, in Spain there is no link to La Niña.
