It has also been informed that the effect of ‘El Nino’ situation may not be much before monsoon this year.

A severe fire is going on across India. There is a cry for rain everywhere in the blazing sun. At such a moment, the country’s Central Meteorological Department (IMD) announced relief. The organization said that this year there will be more than normal rainfall.

On Monday (April 15), the IMD informed that there is a possibility of six percent more rainfall than normal across India this year. India’s average rainfall this year is likely to be 87 percent.

It has also been informed that the effect of ‘El Nino’ situation may not be much before monsoon this year. La Nina may also remain weak. Usually, when such conditions exist, an environment conducive to precipitation is created.

Looking at the rainfall patterns for several years from 1971 to 2020, the IMD said 20 of the 22 years when ‘La Nina’ was active saw normal or above-normal rainfall. The only exceptions were 1974 and 2000.

Southwest Monsoon usually enters India through Kerala on 1 June. Due to the effect of this wind, the rain continues until the end of September. That is the declared monsoon-calendar of this country. But this time is often changed.

According to the IMD, this spring saw less snow in the North Pole than last time. It has an inverse relationship with the southwest monsoon. All in all, India will get more rain than normal this time according to the forecast of Meteorological Department.

A few days ago, India’s Central Meteorological Office had issued a summer heatwave warning. This year, the Lok Sabha elections in India will be held throughout the summer. So many people were alarmed by the announcement of the Meteorological Department. However, their new announcement put many at ease. Farmers got the logistics to be assured of farming.

Incidentally, ‘El Nino’ (which means little boy in Spanish) occurs in countries along the eastern coast of the Pacific Ocean in South America, including Chile and Peru. This situation returns every two to seven years. As a result, the temperature of the ocean water level (sea surface) increases by 2 to 4 degrees Celsius. As a result, the atmosphere of the coastal area also heats up. Due to this situation, the current of warm water from the western edge of the Pacific Ocean flows to the eastern side of the ocean. As a result, the warm water on the east coast increases the temperature of many areas of land adjacent to the ocean.

At that time, cold water cannot rise from the bottom of the sea. As a result, the water level at the back of the sea does not get a chance to cool down. And in ‘La Nina’, the exact opposite happens. When ‘El Nino’ is active, the temperature of the earth increases and when it is weak, the cooling increases in the opposite reaction. She is called ‘La Nina’ (meaning little girl in Spanish).
