What happens as a result of El Niño?
During an El Niño event, the surface waters in the central and eastern Pacific Ocean become significantly warmer than usual. It also reduces the upwelling of cooler, nutrient-rich waters from the deep—shutting down or reversing ocean currents along the equator and along the west coast of South and Central America.
What is the effect 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.
How does El Niño affect precipitation?
El Niño occurs when warm water builds up along the equator in the eastern Pacific. The warm ocean surface warms the atmosphere, which allows moisture-rich air to rise and develop into rainstorms. During El Niño years, such as 1997, the southeast receives more rain than average.
What are the causes and effects of 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 is the effect of El Nino on Indian monsoon?
In a phenomenon called El Nino, warming of sea surface temperatures in eastern equatorial Pacific, near the Peru coast — or the cooling effect in the same region called La Nina — affects the Indian southwest monsoon negatively or positively.
How does El Niño affect the hydrosphere?
El Nino affects the hydrosphere because the water gets to be a lot warmer in the East Pacific and a lot colder in the West Pacific. The currents are also affected. La Nina affects the hydrosphere because the water is very cold in the east Pacific and in the middle of the Pacific, too.
What are the negative effects of El Niño on agricultural production?
The drought conditions due to El Niño have a direct negative impact on maize production and long term crop production statistics analysis carried out by WFP show that drops in maize yield are clearly more frequent during El Niño seasons particularly for South Africa (largest producer) and Zimbabwe (most food insecure).
Is El Nino good or bad?
El Nino and Michigan: Winter outlook looks good or bad. An El Nino is warmer-than-normal sea water in the Pacific. La Nina is cooler than normal Pacific sea surface water. In an El Nino the warmer waters flow towards the east, in other words towards the United States west coast . The opposite happens in an La Nina. IT IS NOT A STORM.
How does El Nino affect us?
When El Nino causes the waters in the Pacific region to warm up, it releases an amount of energy so large into the atmosphere that impacts the weather patterns all across the globe. El Nino causes natural disasters, such as droughts or flooding, by either cutting the amount of rainfall or increasing it.
What are the impacts 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.
How does El Nino affect weather?
Although El Niño’s strongest impacts are felt around the equatorial Pacific, they can affect weather around the world by influencing high and low pressure systems, winds and precipitation. And as the warmer ocean waters release excess energy (heat) into the atmosphere, global temperatures rise.
