What year did El Nino occur? What extreme weather is easy to occur in El Nino year?

The natural geographical environment we live in is composed of topography, climate, plants, soil, biology and many other factors, among which climate is one of the important natural geographical factors and refers to the average state of the atmosphere for many years. The atmosphere has been stable for a long time, but the global climate is constantly changing. The factors affecting global climate change can not only come from nature, but also from human activities. What human activities are most familiar with global climate change is "global warming". On the one hand, human beings widely use fossil fuels such as coal and oil, and emit a lot of carbon dioxide. On the other hand, human beings have destroyed the green plants on the earth and weakened the ability to absorb carbon dioxide. These two effects increase the content of carbon dioxide in the atmosphere, strengthen the heat preservation function of the atmosphere, and bring about an increase in the global average temperature.

Global warming is not only as simple as the global average temperature rise, but also has a wide impact on sea level rise, ecosystem changes, natural disasters, extreme weather and climate events. One of the most famous extreme weather El Nino phenomena is El Nino from Peru, South America, which was originally discovered by local fishermen as a climate anomaly. The Pacific Ocean in western Peru is affected by the Peruvian cold current, and the seawater temperature is generally low. The rising cold current, such as the Korean Wave in Peru, coupled with the rich nutrition of the mud on the seabed, formed a famous Peruvian fishing ground and bought a large number of cold-water fish. However, fishermen in Peru's coastal areas found that around Christmas (165438+ 10 to March of the following year), the abnormal warming of Peru's cold current led to the death of a large number of marine fish. Local fishermen call it El Nino.

It rained heavily in the south of China. According to the monitoring data of the Central Meteorological Observatory, the cumulative rainfall in many places south of the Yangtze River in southern China exceeded 100 mm in the week from June 2 to June 9. Especially in Yongchuan, Guilin, Guangxi, the cumulative rainfall monitored in one week reached 694 mm. What is this concept? The average annual rainfall in Beijing is only 600 mm, and it rained in Yongchuan, Guilin for one year. The total rainfall in Longmen, Huizhou, Guangdong Province is 852 mm, which is close to 1000 mm, which is further exaggerated! It rained so much in such a short time that the flood disaster accelerated and the water level soared in many places.

As of June 9 14, affected by floods in southern China, 2.627 million people in Guangxi, Guizhou, Guangdong, Jiangxi, Hunan and Fujian 1 1 provinces (autonomous regions and municipalities) were affected and 228,000 people were resettled. /kloc-more than 0/300 houses collapsed. The direct economic loss was 4.04 billion won. Wang Yongguang, chief forecaster of the National Climate Center, said that in late spring and early summer, the temperature in North China was relatively high, and rainfall in the middle and lower reaches of the Yangtze River was one of the characteristics of weather-related coping between north and south.
