See how El Niño intensity has grown over the past 400 years.

El Nino - the deviation of the temperature of the ocean surface in the equatorial part upwards from the average

values ​​that leads to climate change indifferent regions of the Earth: in particular, affects the amount of precipitation and weather. Climatologists predicted its appearance in 2019 at the level of 85% - this can lead to severe droughts and climate change.

The last such phenomenon occurred in 2015. Then more than 100 million people in southern Africa, Asia and Latin America due to droughts faced water shortages.

This year, El Nino formed not inEastern Pacific, in which it is traditionally formed, and in the central. This phenomenon is called El Nino Modoci and affects not only precipitation in the Americas, but also in the region of Southeast Asia.

El Nino frequency in the central Pacific relative to El Nino frequency in the eastern Pacific

According to research, despite the fact thatEl Nino Modoci is usually not as strong as its eastern counterpart, gradually this type of climate phenomenon begins to prevail. Over the past 400 years, on average, two types of El Niño succeeded each other in turn, but during the previous two decades, Modoci was formed three times more often than its eastern counterpart.

In addition, El Nino Modoci begins to increase in comparison with what it was in the middle of the twentieth century. It is not yet clear what can be associated with a sharp increase in this phenomenon.
