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 are two negative environmental consequences of El Niño?
| Condition: Effect: | droughts crop failure increase in disease due to lack of water for sanitation and hygiene blowing dust pollution of viable water sources decrease in near-shore coastal water quality |

What are the effects of El Niño on the environment?
El Niño
causes the Pacific jet stream to move south and spread further east
. During winter, this leads to wetter conditions than usual in the Southern U.S. and warmer and drier conditions in the North. El Niño also has a strong effect on marine life off the Pacific coast.
What are two effects of El Niño?
(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 negative effects of El Nino and La Nina?
El Niño and La Niña affect
not only ocean temperatures, but also how much it rains on land
. Depending on which cycle occurs (and when), this can mean either droughts or flooding. Typically, El Niño and its warm waters are associated with drought, while La Niña is linked to increased flooding.
What are 3 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.
What are La Nina conditions?
The Short Answer: La Niña is
a weather pattern that occurs in the Pacific Ocean
. In this pattern, strong winds blow warm water at the ocean’s surface from South America to Indonesia. As the warm water moves west, cold water from the deep rises to the surface near the coast of South America.
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 a positive effect of El Niño?
On the other hand, in the United States, El Niño typically
brings wet weather to California
(benefiting lime, almond, and avocado crops, among others), warmer winters in the Northeast, increased rainfall in the South, diminished tornado activity in the Midwest, and a decrease in the number of hurricanes that hit the …
What are the good effects 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)
What are the causes and effects of El Niño?
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. 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 causes and effects of El Niño phenomenon?
Primary Causes of El Niño
In normal conditions,
the wind blow from the east to the west along the equator in the Pacific
. … Accordingly, these elements make the water in the pacific warmer which results in El Niño events. Besides, the warmer ocean successively affects the winds which make the winds weaker.
What is El Niño effect?
El Nino is a climate pattern that
describes the unusual warming of surface waters in the eastern Pacific Ocean
. El Niño has an impact on ocean temperatures, the speed and strength of ocean currents, the health of coastal fisheries, and local weather from Australia to South America and beyond. …
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.
What is El Niño effect Class 9 Ncert?
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 the effect of El Niña?
One important global impact of La Niña is its effect on the Atlantic hurricane season. La Niña
reduces wind shear—the change in winds between the surface and the upper levels of the atmosphere
—allowing hurricanes to grow.
