What is El Nino and what are the consequences?

What is El Niño and what are the consequences?

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 causes El Niño effect?

An El Niño condition occurs when surface water in the equatorial Pacific becomes warmer than average and east winds blow weaker than normal. During this phase of ENSO, the water is cooler than normal and the east winds are stronger. El Niños typically occur every 3 to 5 years.

What are the effects of El Niño in the Philippines?

El Niño is caused by the warming of sea surface temperature in the Pacific and can affect air and sea currents. This phenomenon resulted in reduced rainfall that led to dry spells, droughts and stronger typhoons. El Niño lasted for 18 months in the Philippines and officially ended in July 2016.

What are two effects 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.

How does El Niño affect sea creatures?

An El Niño reduces the upwelling of cold water off the coast of the Americas. When this happens, fish either die or migrate into areas where they’ll find more to eat. Marine mammals, such as seals and sea lions, that feed on fish may be affected.

How does El Nino affect the Philippines?

What is El Nino effect 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 El Nino and what are its effects?

What is “El Niño” and what are its effects? The term El Niño (Spanish for ‘the Christ Child’) refers to a warming of the ocean surface (or above-average sea surface temperatures) in the central and eastern tropical Pacific Ocean.

How are El Nino and La Nina weather patterns related?

El Niño and La Niña are complex weather patterns resulting from variations in ocean temperatures in the Equatorial Pacific. La Niña is sometimes referred to as the cold phase of ENSO and El Niño as the warm phase of ENSO. These deviations from normal surface temperatures can have large-scale impacts not only on ocean processes,…

What happens to fish during an El Nino?

An El Niño lessens the upwelling of cold water and the uplift of nutrients from the bottom of the ocean. As a result, fish either migrate to other regions or die during an El Niño because they lack adequate food for growth and survival.

What is the opposite of an El Nino?

An El Niño condition occurs when surface water in the equatorial Pacific becomes warmer than average and east winds blow weaker than normal. The opposite condition is called La Niña.
