What is the impact of El Nino on Chongqing? Expert analysis

What is the impact of El Nino on Chongqing? Expert analysis is as follows:

The influence of El Nino phenomenon: the sea surface temperature along the Pacific coast rises abnormally, the sea water level rises, and a warm current flows south.

It turns cold water in the East Pacific into warm water, causing tsunamis and storms, causing drought in some areas and excessive rainfall in others.

El Nino has a serious impact on China's climate: the number of typhoons has decreased. After El Nino, the number of tropical storms (typhoons) in the northwest Pacific and the number of landings in China's coastal areas are less than normal.

scientific research

The equatorial wind blows warm water to the west, and cold water surges up along the coast of South America.

Meteorologists' research on El Nino still stayed in the late 1960s. They consulted the weather archives for more than 30 years since the Second World War and found that several major "El Ni? o" phenomena occurred during the year, and all of them had global weather anomalies.

1972 global weather anomalies are related to the particularly strong El Ni? o warm current that year. This year, the worst national drought occurred in China since the founding of New China. At the same time, serious floods have occurred in some countries and regions, such as Tunisia in Africa, which is once in 200 years, and Peru is the worst flood in 40 years.

Warm water is blown to South America, and cold water is no longer upwelling to warm the ocean.

At the end of 1982, the El Ni? o warm current reappeared, and the sea water in the eastern Pacific near the equator increased abnormally, and the scope became larger and larger. Around Christmas, more than 1700 seabirds perched on Christmas Island disappeared. Then it rained heavily and flooded in Peru. By 1983, El Nino had spread all over the world, and abnormal weather appeared continuously in America, Asia, Africa and Europe.
