El Nino: Past, Present, and Future Essay example

It is well known that politics and religion are two topics to never to be discussed with someone one does not know well. In today’s society, it feels as if this list of topics that are socially deemed inappropriate to discuss seems to be growing, with climate change now being a conservation to avoid. This aversion to discussing climate change appears to stem from the fact that the issue tends to polarize opinions, in which people fall into one of two groups: climate change skeptics and climate change believers. This paper seeks to address and analyze the ways in which climate skeptics speak about and understand climate change as well as how climate scientists understand climate change phenomena. More specifically, this paper focuses on how climate skeptics comprehend the relationships between grasslands, livestock, methane and nutrient cycling and how these interconnected concepts do not lead to the type of climate change that “green urbanities /green politicians/green activists/green elite” predict. The paper will conclude with an evaluation of the two differing positions between climate skeptics and climate scientists, in which I will determine which argument I find to be the most accurate.

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

Cumulonimbus clouds are mostly affiliated with thunderstorms, lightning, heavy rainfall, blizzard or hail. The forecast should reflect rain or chances of rain.

It is important to understand the various cycles our atmosphere goes through due to how they affect our daily lives. The ENSO Cycle has a large impact globally and locally in California as we have seen with the long-term drought Southern California is currently in. The ENSO cycle can be defined by sea surface temperature (SST) anomaly in the Pacific Equatorial Area known as Nino 3.4 region (5oN-5oS, 120o-170oW). Unusually cooler waters (-.5 degrees centigrade) occurring for three consecutive months outlines a La Niña. La Niña’s bring wetter weather to Australia and Indonesia but often leaves the Eastern Pacific dry. Unlike La Niña’s, unusually warm water (+.5 degrees centigrade above average) occurring for 3 consecutive month’s outlines an

el nino is a warm band of water that periodically develops in the Pacific Ocean near the equator off western South America. El Niño—Spanish for “the child” because it often occurs around Christmas—occurs about once every two to seven years. El Niño can affect the weather in large parts of Asia, Africa, Indonesia, and North and South America, causing both floods and droughts. An El Niño event is often followed by a band of colder than normal ocean waters called La Niña, which is Spanish for “the girl.” La Niña produces the opposite weather conditions. Both of these phenomena cause changes in air pressure in the western Pacific. Together these two events are known as ENSO, or El Niño–Southern

Changes are occurring in the Precipitation level. More hotter in summers are than normal leading to more storms.

Easterly Trade Winds over the equatorial Pacific Ocean are partially to blame for both occurrences. For La Niña, the Easterly Trade Winds substantiate her atmospheric conditions. The Winds blow added warm water west, which causes very cold water below the ocean's surface to rise upward toward the surface replacing the warm water, and this occurs near the South American coast. During an El Niño, the opposite occurs. The Easterly Trade Winds become weaker causing a lessened, to no impact, at all. The Winds can even reverse direction. The warm Pacific Ocean becomes nearly stationary or flows eastward and as it does, it gains heat because there is little or no circulation of air. Not only does El Niño affect weather, it is also responsible for

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.

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

scientific term that describes the fluxes of the temperatures between the ocean and the atmosphere in the central-eastern equatorial pacific. La Nina is the cold phase of the cycle with El Nino being the warm phase in ENSO cycle. This cooling of water have an impact on global weather and climate. Due to La Nina there are stronger wind currents in the pacific and impacts on Australian rain patterns.

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.

Monsoon season has led to changes in temperature worldwide. As an example, the seasonal temperature anomalies from June–July–August (Northern Hemisphere summer, Southern Hemisphere winter). The surface temperature anomalies relative to the base period from 1951 to 1980 are shown in Figure 1 for mid-decade years of the 1950s, 1960s, and 1970s, and for the past six years. Most regions in recent years are warmer than during 1951 to 1980. However, some areas are cooler than the 1051 to 1980 mean occur every year. For example, the United States was unusually cool in the summer of 2009. Research shows that global warming since 1951 to 1980 is about 0.5-0.6⁰C (about 1⁰F). Even though this seems small compared to weather fluctuations. This level of

This summer we've already been slightly impacted from El Niño. Near the Caribbean Sea and the other parts of the Atlantic basin there's been strong wind shear. El Niño occurs when there's warming of ocean water in the Pacific Ocean. El Niño occurs in a cycle of three to seven years. El Niño will be present winter 2015-2016 and will weaken towards spring. In the United States El Niño lasting into spring is important because precipitation and temperature go from moderate to storm. El Niño can cause major damage to our agriculture,people, and many other

Over the years there has been a lot of controversy on if climate change is an issue that needs to be discussed and solved. There is a constant debate among scientist on if human actions are contributing the changing of earth’s climates. Climate change is defined as the change in average weather patterns for a specific region or Earth as a whole. This could include the change in an average temperature for a city or the amount a rainfall it receives (Dunbar, 2015). The main difference between weather and climate is the period of time specific patterns are recorded. Weather patterns are looked at over a much shorter period of time, meaning that these patterns are going to be more sporadic and change more frequently. Climate on the other had is recorded over a much longer period of time and usually show less drastic changes in patterns when compared to weather. Some people may argue that climate change is not an issue because Earth’s temperature is always changing do to natural effects. What people don’t realize is that human activity has effected the rate that earth’s temperature is changing, and just the smallest changes can lead to drastic consequences (Dunbar, 2015).

Scientists have discovered 'climate forcing’s ' influence variations in climate systems and based on the depth and period of such forcing’s the adjustments to climate may be in a shorter or longer earth cycle. Natural forcing’s like variations in earth 's orbit, solar variation, volcanic eruptions and motion of tectonic plates have influence on the Earth 's climate
