In 2018, America can return the»El niño» climatic phenomenon of fluctuations in the temperature of surface water in the Pacific that affect weather throughout the southern hemisphere.
The probability of the return of «El niño» this year, about 70%, said meteorologist Centre for climate prediction in Maryland (NOAA»s Climate Prediction Center) Michelle L area. According to her, the climate phenomenon will unfold, not with a record, but the weather changes are still very noticeable.
The probability of the arrival of «El niño» meteorologists predict, by measuring the surface temperature of ocean water in several regions. In recent weeks it became noticeably warmer and the trade winds coming off the coast of South America. However, not all dependent on changes in the Pacific ocean — is crucial how the ocean water will circulate in the atmosphere.
In California, for example, «El niño» can cause heavy precipitation, while in other regions, on the contrary, there may be a drought. It all depends on the intensity fluctuations of the upper layer of water in the Pacific ocean. Typically the «El Nino» comes in late summer and lasts throughout the fall and winter, affecting weather conditions in the Pacific waters, but also in the Indian ocean.
Steaming, warm ocean water warms the air. So, 2018 and 2019 years can be in the top 5 of the hottest summer seasons. The last «El niño» — in the period from 2015 to 2016 — was one of the most powerful in history. Then for the Christmas holidays in the USA and South America were heavy rains.
