Elnino: A Global Impact On Weather Patterns

One of the biggest tectonic events that has an effect on the earth climate is volcanic activity.

where the warm waters helped it to develop stronger. When it made landfall it killed about four

Global climate change is more than just raising the concentration of GHG’s in the atmosphere, it’s a serious health threat. Dr. Howard Koh, of the Harvard T.H Chan School of Public Health, has stated that global warming is a threat to human health because of an increase in respiratory and allergy aggravation,

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

Climate Change Letter Paragraph 1: Introduction and Thesis Climate change is a big problem that we have now in the present, and we have to care about is we want a better future. We need to use renewable energy like the wind turbine, and solar panels. We need to pay attention to this giant problem, and we have to change our minds and help our planet. So Donald Trump, change your mind and help the USA to have more solar panels, and renewable sources, so you can save the future of all.

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

The Southern Hemisphere is warmer in December, January, and February because it receives more solar energy than does the Northern Hemisphere. During, June, July, and August the opposite is true; the Northern Hemisphere receives more solar energy and is warmer. This is due to the spherical shape of the planet, due to which sun is nearly overhead at equator than at high latitude therefore warmest. Thus, temperature varies with latitude from the warm Equator to the cold poles.

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?

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.

The maritime polar air mass is a very moist eastward bound airmass. This system is charterised as an oceanic air mass with high mosture levels and modest sesonal temperature changes.

The Circulation of the world’s oceans can be divided into the upper and the lower. The upper few 100 metres movement is generally wind-driven whereas below this, circulation is driven by the heating and cooling of waters producing regional density differences. This creates the ‘Thermohaline circulation’ (THC), otherwise known as the Great ocean conveyer, an overturning circulation system.

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

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.

“Natural disasters have killed more than 600,000 people and left behind trillions of dollars in damages in the last two decades, the United Nations said Monday.” (Chan) Extreme weather has caused millions of casualties and extreme damages over the years, but lately there has been an increase in severe weather events. This is causing problems in the US, with the amount of tornadoes rising in tornado alley “Tennessee experienced a 67 percent increase in tornado activity in 1983-2013 compared to the 1954-1983 time period. Oklahoma experienced a nearly 35 percent decrease in tornadoes in 1983-2013 compared to 1954-1983.”
