The phenomenon of La Nina is weakening and probably in April there will be a transition to the neutral phase Enso – the American climate forecast center (Climate Prediction Center). She added that data analysis shows that this situation can stay in the northern hemisphere throughout the summer.
According to American meteorologists, La Nina's weather anomaly is coming to an end and soon the neutral Enso phase may occur.
“In the period of June -August, the probability of the enso neutral phase is 62 percent, and in July -September – 50 percent”, “the American climate forecast center (CPC) said on Thursday in its monthly forecast.
Enso (El Nino-Southern Oscillation) is a natural, cyclical meteorological phenomenon, resulting from changes in the wind and surface temperature of the Pacific. It combines two opposing phases: warm El Nino and the cold La Nina. The enso neutral phase is a transitional period between them.
La Nina and El Nino – what are these phenomena
La Nina occurs when the surface temperature of the Pacific Ocean around the equator, especially off the coast of South America, is lower than the average. Increased activity of straps in this part of the world contributes to this. During the La Nina anomalies, extremely dry conditions prevail in South America or the Mexican Gulf, and Australia is haunting floods.
The opposite phenomenon is El Nino, during which the temperature on the surface of the water in the Pacific Equatorial Zone is above average high. The phenomenon is also associated with the weakness of the straps. When El Nino occurs, especially dry conditions occur in Indonesia, over Amazon and Central America. In addition, rainfall in sub -Saharan Africa is increasing.

Japanese calculations
Also from the calculations of experts from the Japanese Meteorological Agency (JMA) shows that La Nina's weather anomaly is weakening. On Monday, scientists reported that there is a 60 % probability that the ENSO neutral phase will stay in the northern hemisphere from spring to summer.
Influence on agriculture
– La Nina was practically over. The anomaly of the sea surface in the Pacific region around the equator is close to zero. Our calculations show that on (American – editor's note) the large plains will be dry for at least a month, which will affect the growth of winter wheat – said Donald Keeney, a meteorologist at Maxar, dealing with data analysis from land observation. – We also anticipate that in May and June, drought will appear in Central Brazil, which will affect corn. In Eastern Europe, Ukraine and Western Russia, until June, more dry conditions will probably remain, which will affect both winter wheat and early corn and sunflower growth, 'added Keeney.
