Impact of El Nino
What is the impact of El Nino
Worldwide
- Temperature :
The Earth's temperature rises by about 0.2°C globally because in El Niño, warm ocean water spreads farther and stays closer to the ground, making the air hotter and more humid, releasing more heat into the atmosphere.
- Climate :
Reduced rainfall in certain regions and increase in extreme weather events, including floods, droughts, landslides, and rising sea levels.
The reason is that when the El Niño phenomenon occurs, warm sea water moves south and east along the Pacific jet stream.
Rainfall is increasing in the southern United States and Mexico, while the northern United States and Canada are experiencing dry weather. In South America, southern Uruguay, Paraguay, and southern Brazil receive significantly more rain than average during the winter. If it gets worse, rivers may overflow, causing thousands of victims. Droughts also occur in Asia, Australia, central Africa, and eastern and southern Africa.
- Industries and Systems :
Adverse impact on food system which is production volume and these occur price inflation. Extreme weather events impact global infrastructure, food, and energy systems.
El Niño caused a drought in Canada and Asia, leading to poor harvests. When El Niño occurs, cold, nutrient-rich seawater does not sufficiently upwell the American coast, leading to a decrease in food for marine species such as squid and salmon, resulting in a decrease in catches in South America.
According to the World Food Program (WFP), significant declines in grain production in certain countries will lead to further price fluctuations, and in regions highly dependent on imports, consumers are facing food insecurity due to rising grain prices.
Korea
- Temperature :
In some areas, temperatures tend to rise due to El Niño. In particular, temperatures rise in the winter, and the growing season of crops may change in the spring due to climate change.
- Climate :
Precipitation in Korea generally increases during El Niño periods. In particular, flooding damage due to heavy rain may occur in the western part of the Korean Peninsula.
These heavy rains mainly affect areas where heavy rains are concentrated, depending on their geography.
Precipitation in Korea increases during the El Niño period in July and August.
In September, when El Niño develops, precipitation tends to decrease and temperatures tend to drop.
In early winter, when El Niño develops at its peak, precipitation and temperature tend to rise on the Korean Peninsula.
- Industries and Resources :
Flooding damage from sudden heavy rain or drought from a strong heat wave can reduce crop yields. Additionally, damage from flooding due to sudden heavy rain and water resource shortages due to drought may occur.
