Is the El Nino year necessarily a warm winter?
El Nino will lead to an abnormal increase in water temperature in the equatorial eastern Pacific, thus affecting climate change, leading to an increase in global temperature and a change in rainfall distribution. Therefore, when El Nino occurs, it usually brings warm winter weather. El Nino phenomenon will also affect global fisheries, agriculture, water resources and other aspects, and even lead to natural disasters, such as hurricanes, floods, earthquakes and so on. Therefore, for many countries and regions, the impact of El Ni? o phenomenon is very important.
On 20 15-20 16, a super El Nino occurred in the Pacific Ocean, and the tropical Middle East Pacific El Nino was considered as the strongest "century El Nino" since 1997- 1998. However, in June of 20 16 and 1 2008, Guangdong, China was hit by a "overlord-level cold wave" snowfall. So we can't see that El Nino will definitely warm winter, because warm winter is a big climate concept, and short-term cold wave and staged low temperature can't be ruled out.
Weather phenomenon of El Nino warm current
In normal years, trade winds prevail in the southeast of this area. The easterly stress on the equatorial surface transports surface warm water to the western Pacific Ocean and accumulates there, which leads to the rise of sea level and seawater temperature there. The upwelling cold seawater is rich in nutrients, which makes plankton multiply and provides sufficient bait for fish. The prosperity of fish provides abundant food for fish-eating birds, so there are many birds here.
El Nino's impact on climate is most significant in the equatorial Pacific. In the El Nino year, Indonesia, Australia, the South Asian subcontinent and northeastern Brazil all experienced drought, while it was rainy from the equatorial central Pacific to the west coast of South America. El Nino will bring devastating effects, which may lead to floods in Latin America, droughts in Australia and crop failures in India.
