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 causes El Niño phenomenon?
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 is El Niño phenomenon Class 9?
El Nino: This is a name given to the periodic development of a warm ocean current along the coast of Peru as a temporary replacement of the cold Peruvian current . ‘El Nino’ is a Spanish word meaning ‘the child’, and refers to the baby Christ, as this current starts flowing during Christmas.
What is El Niño phenomenon 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 is El Niño phenomenon explain its causes and effects?
The warm water in the west heats the air , making the warm air rise and leading to drastic weather, including rain and thunderstorms. The rising warm air causes a circulation between east and west in the Pacific, with the warm, moist air rising in the west, and cool, dry air descending in the east.
What are 2 effects of El Niño?
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.
How can we reduce the effects of El Niño?
- Evaluate your Property.
- Protect Against Soil Erosion.
- Use Sustainable Flowers, Shrubs, and Trees.
- Keep a Watchful Eye on Your Trees.
- Keep Storm Drains Clear.
- Maintain Parking Lots and Walkways.
What is the effect of El Niño Class 9?
El Nino refers to the large-scale ocean-atmosphere climate interaction linked to periodic warming in sea surface temperatures across the central and east-central Equatorial Pacific . It is associated with high pressure in the western Pacific. El Nino adversely impacts the Indian monsoons and hence, agriculture in India.
Is La Nina good for India?
La Niña phase ends, neutral conditions likely to support good rains in India. ... In India for example, El Nino is associated with drought or weak monsoon while La Niña is associated with strong monsoon and above average rains and colder winters.
What is Southern Oscillation Class 9?
Southern Oscillation, in oceanography and climatology, a coherent interannual fluctuation of atmospheric pressure over the tropical Indo-Pacific region . The Southern Oscillation is the atmospheric component of a single large-scale coupled interaction called the El Niño/Southern Oscillation (ENSO).
What are the impacts of El Niño and La Niña to the Philippines?
The climate of the Philippines is highly influenced by the El Niño Southern Oscillation (ENSO). El Niño is associated with an increased chance of drier conditions and La Niña is associated with an increased chance of wetter conditions.
What are the effects of La Niña in the Philippines?
When La Niña hits, the water level rises rapidly. The spill gates have to be opened to prevent an overflow of the dams . The result of such openings are often floods in the lowlands.
What are the effects of La Niña?
La Niña causes the jet stream to move northward and to weaken over the eastern Pacific . During La Niña winters, the South sees warmer and drier conditions than usual. The North and Canada tend to be wetter and colder. During La Niña, waters off the Pacific coast are colder and contain more nutrients than usual.
How El Niño affect people?
What is the humanitarian impact of El Niño? El Niño and La Niña can make extreme weather events more likely in certain regions, including droughts, floods and storms. Over 60 million people were impacted by the 2015/2016 El Niño although an exact number is hard to pinpoint.
How does El Niño affect humans?
El Niño has affected food security and agricultural production , with cascading effects on livelihoods, health, water, sanitation, education and other sectors. This is due to flooding, disease outbreaks and malnutrition, disruption of health and education services, and overall increased mortality.
What is a positive effect of El Niño?
Fewer hurricanes and other tropical cyclones in the north Atlantic. Milder winters in southern Canada and the northern continental United States. Replenishment of water supplies in the southwestern U.S. Less disease in some areas due to drier weather (like malaria in southeastern Africa)
