What were the possible effects of the 1997 1998 El Nino season?
Losses from the El Niño in 1997-1998 included thousands of deaths and injuries from severe storms, heat waves, fires, floods, frosts and drought. Estimates of El Niño-related damage ranged from $32 to $96 billion. would otherwise be distributed in the west Pacific and elsewhere at sea.
What occurred due to the 2016 El Niño?
The 2014–2016 El Niño was a warming of the eastern equatorial Pacific Ocean that resulted in unusually warm waters developing between the coast of South America and the International Date Line….2014–2016 El Niño event.

How much damage did the largest El Niño La Niña in 1997 cause?
Back in 1997-’98, a massive El Niño in the Pacific Ocean pushed global temperatures to new highs and triggered a spate of extreme weather around the world, ultimately causing some $35 billion in damage and 23,000 deaths.
What was the negative effect of 1997/98 El Nino on the earth?
The El Niño and La Niña phenomena have implications for climate in both hemispheres. The 1997/98 El Niño phenomenon, which started in March 1997 and lasted until mid-1998, had resulted in severe flooding and drought in several parts of the world .
What did 1997 El Niño cause?
The 1997–1998 El Niño was regarded as one of the most powerful El Niño–Southern Oscillation events in recorded history, resulting in widespread droughts, flooding and other natural disasters across the globe.
What are the economic consequences of an El Niño year?
The higher temperatures and droughts following an El Niño event, particularly in Asia and the Pacific, not only increases the prices of nonfuel commodities (by about 5½ percent over a year), but also boosts demand for coal and crude oil as lower output is generated from hydroelectric power plants, thereby driving up …
What are the global effects of El Niño?
During an El Niño event, sea surface temperatures across the Pacific can warm by 1–3°F or more for anything between a few months to two years. El Niño impacts weather systems around the globe, triggering predictable disruptions in temperature, rainfall and winds.
How does El Niño affect disease?
It can be a bit complicated, but the short answer is that the temperature and precipitation patterns driven by ENSO can alter the habitat of disease transmitters, such as mosquitoes or rodents, or make conditions more conducive for waterborne diseases, such as cholera.
What are the effects that El Niño causes?
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 the effects of El Niño and La Niña?
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 the effects of El Niño in the country?
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 positive effects 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 some global consequences of El Nino?
El Niño, La Niña, and the neutral condition all produce important consequences for people and ecosystems across the globe. The interactions between the ocean and atmosphere alters weather around the world and can result in severe storms or mild weather, drought or flooding.
What are the positive effects of El Nino?
Mild winter temperatures over western Canada and north western USA
What is caused by El Nino?
Weaker winds means the ocean gets warmer and this process happens interchangeably and consecutively thus making the El Niño bigger and bigger. In other words, El Niño is caused by the weakening of the trade winds which results in pushing of warm surface water to the west and less cold water to the east.
What are the economic impacts of El Nino?
– Benefits to U.S. – Benefits in U.S. – Even in the small Northwest Coho salmon fishery, annual benefits are estimated at $250,000 to $1 million from changing hatchery releases and harvest rates. – Further, better forecasts reduce uncertainty and improve new insurance systems like the $7+ billion weather derivatives market by improving price risk projection.
