The El Nino : A Weather Phenomenon

We might disagree on the causes of global warming; however, we cannot ignore that it is happening. Although we still experience cold winters, average global temperatures has risen drastically for the past three decades. Polar ice caps are melting; as a result, sea levels are rising. Scientist predict more extreme weather in the coming decades, in fact, droughts will probably be more common. Also, flooding and tropical temperatures might cause large amounts of methane gases to be released, which could be disastrous for our atmosphere. Climate change may have human causes and also it might be a natural occurrence. Nevertheless, we must find ways to save our planet.

The El-Niño Southern Oscillation is a complex sequence of natural climate variations that take place in the tropics of the Pacific Ocean, yet affect the climate of the entire globe. The climate phenomenon, known as ENSO, has three main phases that each differ markedly in their atmospheric and oceanic conditions. El Niño, also known as “the warm phase”, is the first cycle that begins when warm water in the eastern Pacific Ocean shifts to the west toward South America. During El Niño, the east-to-west trade winds halt and sometimes reverse directions, causing significant disturbances in the biological life of the Pacific Ocean. Conversely, La Niña is the complete opposite of El Niño. La Niña, also called “the cold phase” brings unusually strong east-to-west winds and colder temperatures along the equatorial Pacific. Both phases have consequences that affect the regular atmospheric conditions of the world; El Niño is linked to both droughts and floods, La Niña is linked to extreme tropical cyclones and monsoon rains. The climatic events also have relationships to forest fires, economic changes, famine, plagues and widespread crop failure. The study of ENSO is necessary in order to attempt to reveal patterns and key factors that can affect the intensity and severity of this phenomenon that occurs globally on average every two to seven years.

El Nino is referring to the dramatic change that occurs in the walker circulation cell and in other areas but I am going to focus on this specific area, where the usually south-easterly trade winds going from west of South America to Australia and Indonesia across the Pacific Ocean reverse or severely weaken. This occurs usually every 3-7 years and can last between 12-18 months. During an El Nino the warm sea in the western pacific migrate towards the South American coast because they are being dragged across by the winds. This stops the upwelling near South America and means that there are little nutrients in the sea. This lack of

Can El Niño save California from wildfires, wilting crops and weary front lawns? The tropical event which causes the Pacific to warm and generally increases precipitation may be California’s Hail Mary. Indeed, there are reasons climatologists are optimistic about its arrival as California experienced two of its wettest years during two of El Niño’s visits -- in 1982 and 1997. The expectation that the powerful brewing storm will pummel California with precipitation sounds reasonable, but will that be enough? According to a NYT article, the state may just be hard-wired for continued drought and needs a real solution, not a hope and a prayer. Riding into the storm with a yearlong rain deficit, El Niño, the hopeful hero of the drought would theoretically

In the years ahead, climate change will have a significant impact on every aspect of the daily lives of all human beings -- possibly greater even than war. Shifting precipitation patterns and ocean currents could change where and how food crops grow. If icecaps melt and low-lying areas are flooded, as is predicted, entire populations could be forced to move to higher ground. The tsunami of 2004 and Hurricane Katrina, in 2005, provided vivid examples of what large-scale climactic catastrophes entail.

Elnino is a warming cycle in the water that had been warming up every year. Every year the temperature has come to increase. This is very dangerous if the water gets too hot something can happen to the crops air and destroy everything in society if it becomes hotter. For now in 2017 the water cold increase in hurricane season . Thats is not good because it could damage our world even more , by creating more hurricanes. Heer are many topics on Elńino What is El´nino:” 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.”(Jet Propulsion Laboratory)

In the article “New El Nino coming on strong” by Janet Raloff they explain how we might be on the verge of a record breaking El Nino.El Nino is Spanish for boy and it's a set of weather changes that happens every few years bringing heat, rain and drought to different areas.Scientists say it could compete with the “super El Ninos” of 1982 and 1997.The event is the largest it's been for this year .But with the rain El Nino brings to California will it solve our drought?

La Niña is coming. Are we ready? It is the result of the end of a weather pattern called El Niño, and it is the colder phase of it. It is dramatically affecting the countries along the Atlantic Coast, including Asia, Australia, South America, and North America.

Kevin Judd, who writes for a website called Skeptical Science, states that the earth’s temperature is expected to increase by three degrees over the next fifty to one hundred years. He explains that this increase in temperature will result in an increase in extreme weather, such as hurricanes. Humanity is

Unlike a moving storm or hurricane, predicting an El Nino season or phenomenon is more complicated that once thought. Like other public health approaches, using an evidence-based one is best. Even though there is a confirmed relationship between precipitation

For example, EI Nino threatens Peru's anchovy harvest, which could mean higher prices for food. The warm water of Ei Nino keeps the nutrient-rich cold water which procides anchovies with food down at the bottom of the ocean. Anchovies are the primary source of fish meal which is the main ingredient in animal

El Nino is a warm current in the Pacific Ocean that flows southward along South America’s west coast. It usually last nine to twelfth months and returns an average 4 years. Normally deep, cold Pacific waters well up to the surface of the Peruvian and Ecuadorian coast, bringing up nutrients and chilling surface waters and causing climatic changes worldwide. A powerful El Nino in 1982 and 1983 caused severe drought in Australia and Indonesia and an unusually large number of storms in California. During the 1997-98 El Nino, heavy rains caused flooding in Peru, Ecuador, and Argentina; monsoons and cyclones struck Madagascar: and severe storms pelted Texas and the Southeast. More recent El Nino events in 2003 and 2006 were not as devastating.

I think that the article was very interesting. El Niño effects many things. El Niño can affect the weather, the amount of rain a place gets now or later, and the temperature. I would think that dropping the instruments into the winds would be very dangerous. When traveling to make the long journey, why would they need 11 people to go along? If they go along, do those people get paid or is this a free ride? It seems more effective if less people went. Maybe then, they could do more experiments. The model that Dr. Barnson was talking about seemed really neat. Instead of having just statistical models, they have dynamical models that actually show how the real world is. Those models do a better job at predicting an El Niño than statistical models.

The first article or website that I explored was titled Extreme weather. It begins by stating that as the world has warmed, it has triggered several other things in the earth’s climate to be altered. It then goes further into depth specifically naming the factors that have been changing due to the altering of the climate. These factors include: heat waves, droughts, heavy downpours, floods, and lastly, hurricanes (Extreme Weather, 2014).

In the distant future, stronger hurricanes, tsunamis, and tornados are going hit us. In the history of our planet, when the global temperature was 1°C higher, due to Earth's spin axis, there were giant waves strong enough to throw 1000 ton mega boulders out of the sea (Hansen 2016). A study completed in 2015 shows that hurricanes such as Hurricane Katrina may become a more common appearance. (Hall, Hereid 2015). The thousands of homes and lives lost from these storms will indefinitely impede with human advancement.
