Changes Of Enso And Tropical Cyclone Activity

In addition, global climate change will exacerbate these challenges faced by countries and populations. Shifting precipitation patterns threaten to reduce water availability in some regions while inflicting stronger storms on others, increasing both potential droughts and floods. This may increase the frequency of more serious

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

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

The Western United States and Alaska were slammed with massive heat in 2014. Records were broke in North America and across every inhabited continent. The oceans were warmer except around most of Antarctica. Scientists say that the warming of the ocean is, "...providing the energy that fuel damaging Pacific storms.". Along with record breaking heat temperatures, the 2014 year passed 2010 for the warmest year. The top 10 warmest years have occured since 1997. The scientists say this is, "a consequence of human activity and possess profound long-term risks to civilization and nature" (2014 Breaks Heat Record). Scientists say that the most remarkable thing about the 2014 heat record was that it occured without a strong El Nino. An El Nino is

To begin “Decade of Drought” explains how some people all over the world don’t have safe drinking water. For example, Africa’s drought killed many people. “Widespread crop failure caused a famine that killed between 50,000 and 250,000 people”(95). Additional, the article continues to explains how droughts affect the world and shows it with pictures. For example, the picture show how spain's

Researchers don't yet comprehend in subtle element what triggers an El Niño cycle. Not all El Niños are the same, nor do the air and sea dependably take after the same examples starting with one El Niño then onto the next. "There isn't one major reason, which is a reason why we can't foresee this thing consummately," Michelle L'Heureux, an atmosphere researcher said (LiveScience 1). "There is

Global Warming does it yet again. The continuous and dangerous cycle of El Nino and La Nina goes on every 2 to seven years. El Nino pushes warm water into the east Pacific, boosts rain in North and South America but dries the West Pacific. La Nina pushes cold water to tropical central Pacific, and causes tropical precipitation to move to the west. La Nina not only creates huge downpours, but also supercharges the Atlantic hurricanes, and if at a huge level like in 1998- 1999, La Nina can also wreak worldwide havoc with floods and hurricanes. Dr. Cai took a look at the effects of climate change on La Nina with 32 software simulations. Although not particularly alarming, they project disastrous events every 13-23 years. Global Warming alters

El Niño and La Niña are opposite effects of the same phenomenon. They both cause changes in the temperatures between the atmosphere and the Pacific region. El Niño is caused by a change in the wind patterns. The Pacific trade winds go from east to west and the warm ocean water go the opposite direction. Normally the two forces creates a balance in the middle. When the Pacific trade winds are weaker than usual, the warm ocean water rushes to the east and collides with the the west coast of the coastal cities at the east of the Pacific. This causes the average ocean temperature to be much warmer. La Niña is effectively the opposite of El Niño. When the Pacific trade winds are stronger than usual, the warm ocean water is pushed further back to the west. This causes the

In the Pacific Ocean, the eastern portion warms to a greater degree than the western portion (exactly the conditions found during El Niño).” (“El Niño” 5). The effects of El Niño is “development of hurricanes in the equatorial eastern Pacific. Occasionally those hurricanes travel north and drench the coast of southern California, then travel eastward to Texas.”(“El Niño” 3). In conclusion, global warming creates a warm ocean current called El Niño, this causes a domino effect which leads to catastrophic weather events like hurricanes, typhoons, flooding and droughts. To sum it all up, humans must do something to help prevent global warming or else dangerous weather effects will

In a normal year, warm surface water is blown towards Australia. This creates heavy rain to parts of Australia. At the other side, South America experiences some drought. When there is an El Niño, those winds and surface ocean currents reverse the direction. The warm air is moved to South America. This makes the opposite happen, produces rain in South America and drought in

El nino and la nina are total opposites. They usually happen one time every three to seven years near christmas time or mid winter. El nino is a warm pool of water that heats the ocean and takes place in the pacific ocean and normally west of south america.el nino can spread and have effects on many places around the globe.el nino uses the earth's atmosphere to form. using the atmosphere

According to the report published in 2012 by the Intergovernmental Panel on Climate Change, the “[a]verage tropical cyclone maximum wind speed is likely to increase.” This has already come to pass, with recent years seeing the strongest recorded wind speeds of tropical cyclones. Additionally, the rate at which both Category 4 and 5 hurricanes appear around the world has essentially doubled since the 1970s.

El Nino is a phenomena that occurs when the ocean and the atmosphere collide. The warm atmosphere mixes with the water and creates a moisture in the air creating a low pressure system. A high pressure system is created when the cold water reduces the air above it. During a low pressure system the air becomes moist and can create severe tropical storms, on the other hand when there is a high pressure system the cold dry air goes back down and takes away all of the moisture. When combined this can create a high and low pressure forcing the wind in the atmosphere to blow low and the higher air blows higher, causing the ocean to react. The ocean is home to many things including an invisible boundary called the thermocline which divides the warm mixed water on top and the cold calm water on the bottom. When there is a shallow thermocline this creates a small trace of warm water, and a deep thermocline hints there 's a large amount of warm water. Because warm water takes up more space than cold water, the sea level is higher when the thermocline is deep and lower when the thermocline is shallow. We are now aware of a phenomenon similar to El Niño called La Niña, in which conditions are opposite to those of El Niño. El Nino is a phenomena in which warm atmosphere mixes with the water and creates a moisture in the air creating a low pressure system. The ocean is home to many things including an invisible boundary called the thermocline which divides the warm mixed water on top and

The normal wind direction, amount of pressure, and water conditions are influenced by El Nino. Normally, “atmospheric pressure is greater in the eastern Pacific than in the western Pacific…[making] the trade winds blow from east to west” (“Creating an Earth System: El Nino,” 2003, para. 2). The western Pacific’s sea level is greater than that of the eastern Pacific since the winds blowing west bring the water west, too. The water in the west is also warmer because warm water is compiled there; in contrast, the water in the east is shallow and cool because of the rising of the cool water. In the east, the cool air is too dense to make rain and clouds, while in the west, the warm air is able to rise to create rain (Netting, 2003, para. 4). During El Nino, the high pressure in the
