What is El Niño What is its effect short answer?
The Short Answer: El Niño is a weather pattern that occurs in the Pacific Ocean. During this time, unusual winds cause warm surface water from the equator to move east, toward Central and South America. El Niño can cause more rain than usual in South and Central America and in the United States.
What is El Niño and its effects 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 are effects of El Niño and what causes it?
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 is El Niño meaning?
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 is El Niño state its features?
El Nino is a climate cycle in the Pacific Ocean with a global impact on weather patterns. The cycle begins when warm water in the western tropical Pacific Ocean shifts eastward along the equator toward the coast of South America. Normally, this warm water pools near Indonesia and the Philippines.
What are the negative 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 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.
What are the impacts of El Niño and La Niña in our society?
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.
How does El Niño affect the economy?
Taking the temperature These extreme weather conditions can constrain the supply of rain-driven agricultural commodities, lead to higher food prices and inflation, and may trigger social unrest in commodity-dependent countries that rely primarily on imported food.
What are the causes and effects of El Nino?
The effects of El Nino created extreme weather changes, ranging from severe drought to severe flooding. These changes posed drastic problems for the population. Drought caused food insecurity and poverty due to crop failure, and flooding created problems with sanitation and increased the spread of water-borne and communicable diseases.
What is climate condition occurs during El Nino?
Around the world, depending on the location, some of the conditions associated with El Niño include: hot weather and droughts; forest and bush wildfires; heavy rain and subsequent flooding; tropical cyclone activity; typhoons and landslides.
What causes El Nino and La Nino?
El Nino & La Nina El Nino is caused by the periodic shift in wind speed and direction in the tropical eastern Pacific which leads to changes in sea Surface temperatures.
What is the impact of El Nino?
A strong El Nino can have a big impact on global weather patterns because it changes the way air circulates in the atmosphere. These circulations are determined by Earth’s rotation, the angle of its axis relative to the sun, and the position of its landmasses and oceans.
