El Niño is a meteorological phenomenon that occurs in the Pacific Ocean and is characterized by the warming of surface waters along the equatorial region. This warming leads to a shift in the atmospheric and oceanic circulation patterns, resulting in a range of impacts on weather and climate around the globe. Research on El Niño has been ongoing for many decades and has helped to improve our understanding of this complex and influential process.
One of the key areas of research on El Niño has been in understanding the mechanisms behind its formation and evolution. Scientists have identified several key factors that contribute to the development of El Niño, including the interaction between the ocean and the atmosphere, the role of tropical convection and trade winds, and the influence of large-scale atmospheric and oceanic currents.
Another area of focus in El Niño research has been on predicting the onset and strength of future events. Accurate forecasting of El Niño is important for a variety of reasons, including the ability to mitigate the impacts of the phenomenon on agriculture, water resources, and coastal communities. To improve the accuracy of El Niño forecasts, researchers have developed a range of models and tools, including satellite observations, ocean buoys, and computer simulations.
In addition to understanding the causes and predicting the impacts of El Niño, research has also focused on the long-term trends and variability of the phenomenon. Scientists have used paleoclimate records and climate model simulations to examine the history of El Niño and how it may have changed over time. This research has helped to provide insight into the potential impacts of future climate change on El Niño.
El Niño research has had a wide-ranging impact on our understanding of the Earth's climate system and has provided valuable information for decision-makers and policy makers in areas such as agriculture, water management, and disaster preparedness. As our understanding of El Niño continues to improve, it is likely that this research will continue to have significant impacts on society and the environment.

During the 1982—83, 1997—98 and 2015—16 ENSO events, large extensions of tropical forests experienced a prolonged dry period that resulted in widespread fires, and drastic changes in forest structure and tree species composition in Amazonian and Bornean forests.

Trends in Ecology and Evolution. It is thought that there have been at least 30 El Niño events since 1900, with the Major ENSO events were recorded in the years 1790—93, 1828, 1876—78, 1891, 1925—26, 1972—73, 1982—83, 1997—98, and 2014—16. Considerable attention was also given to the collapse of Peruvian and Chilean anchovy populations that led to a severe fishery crisis following the ENSO events in 1972—73, 1982—83, 1997—98 and, more recently, in 2015—16. More generally, these findings pave the way for more such studies investigating the implications of fire-generated pollution for atmospheric circulation, rainfall, and temperatures, in a variety of world regions, both on short weather and on long climate timescales. Given that wildfires emit greenhouse gases and aerosols tiny smoke particles that affect radiation in the atmosphere, it is expected with high confidence that they also result in disturbances to global and regional climate.

New research reveals that wildfires can influence El Niño
Retrieved 1 January 2011. The hypothesis of the new study is that these smoke emissions can drastically influence atmospheric conditions in the western Pacific and therefore modify the development of the El Niño phenomenon itself. We can be the generation to finally end the devastation El Niño has wreaked on humankind for millennia. Retrieved 5 September 2019. Retrieved 7 April 2016. Today, in all likelihood, we stand about a month away from another major El Niño. Retrieved 22 October 2014.

The world's largest fishery collapsed due to overfishing during the 1972 El Niño The ENSO variability may contribute to the great success of small, fast-growing species along the Peruvian coast, as periods of low population removes predators in the area. This fickle and influential climate pattern often gets blamed for extreme weather. Our world is more connected than ever before. El Niño events are thought to have been occurring for thousands of years. We have applied our ingenuity to make the modern world more connected and technologically advanced than ever before.

It can constrain the supply of rain-driven agricultural commodities; reduce agricultural output, construction, and services activities; create food-price and generalised inflation; and may trigger social unrest in commodity-dependent poor countries that primarily rely on imported food.

During strong El Niño episodes, a secondary peak in sea surface temperature across the far eastern equatorial Pacific Ocean sometimes follows the initial peak. We have used "chaos control" methods to control the chaotic behavior of El Niño in a model that is used successfully for predicting El Niño events in the Equatorial Pacific.

Fiji generally experiences drier than normal conditions during an El Niño, which can lead to drought becoming established over the Islands. During recent large El Niño events, such as in 1997 and 2015, this has combined with expanding agricultural land clearance to produce vast fires in peat-dominated areas.

But Their impacts do not restrict only vegetation, since declines in insect populations were observed after extreme drought and terrible fires during El Niño 2015—16. .
