What is El Niño phenomenon PDF?

El Niño events are large climate disturbances which are originated in the equatorial Pacific Ocean, and occur in every 2 to 8 years. It is related with wide-ranging changes in the climate system and can lead to prominent socioeconomic impacts affecting infrastructure, agriculture, health and energy sectors.

What is the phenomenon of El Niño?

El Niño is a climate pattern that describes the unusual warming of surface waters in the eastern tropical Pacific Ocean. El Nino is the “warm phase” of a larger phenomenon called the El Nino-Southern Oscillation (ENSO). El Niño was recognized by fishers off the coast of Peru as the appearance of unusually warm water.

What are the characteristics of El Niño?

During El Niño, the surface winds across the entire tropical Pacific are weaker than usual. Ocean temperatures in the central and eastern tropical Pacific Ocean are warmer than average, and rainfall is below average over Indonesia and above average over the central or eastern Pacific.

What are the effects of El Niño phenomenon?

Severe drought and associated food insecurity, flooding, rains, and temperature rises due to El Niño are causing a wide range of health problems, including disease outbreaks, malnutrition, heat stress and respiratory diseases.

What is El Niño Class 9?

El Nino can be understood as a natural phenomenon wherein the ocean temperatures rise especially in parts of the Pacific ocean. It is the nomenclature which is referred to for a periodic development along the coast of Peru. This development is a temporary replacement of the cold current along the coast of Peru.

What is the impact of El Niño in Africa?

In Africa, El Niño conditions are associated with increased rainfall in East Africa and decreased rainfall in southern Africa, West Africa, and parts of the Sahel.

What causes the El Niño phenomenon?

El Niño occurs when warm water builds up along the equator in the eastern Pacific. The warm ocean surface warms the atmosphere, which allows moisture-rich air to rise and develop into rainstorms.

Is El Niño a natural phenomenon?

El Niño is a climate phenomenon that occurs when a vast pool of water in the eastern tropical Pacific Ocean becomes abnormally warm. Under normal conditions, the warm water and the rains it drives are in the western Pacific. El Niño is one extreme in a natural cycle, with the opposite extreme called La Niña.

What are two features of El Nino?

(i) The presence of the EL-Nino leads to an increase in sea-surface temperatures. (ii) It weakens the trade winds in the regions and causes heavy rainfall, floods or droughts in different regions of the world.

What are the causes of El Nino?

What are the causes of El Niño?

What is El Niño effect class 12?

The El Nino effect refers to uneven climatic changes due to rise in temperature. It leads to increased melting of polar ice caps as well as other places like the Himalayan snow caps. This results in the rise in the sea level which can submerge many coastal areas, thus resulting in biodiversity loss.
