El Nino Essay

1. Is a temperature inversion more likely to form on a calm or a windy night? Why?

4. Scroll down to the section “The Greenhouse Effect is Natural. What do we have to do with it?” What are some ways that humans are thought to be contributing to climate change?

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

This caused more snake bites as mice from the higher elevations came to lower elevations to find food and water while their prey (snakes) followed them. In New Mexico, however, the climate turned cooler and wetter. This caused an increase in the bubonic plague, because the weather conditions were ideal for fleas and rodents. “The mountain and pacific states had severe storms that caused $1.1 billion of damage and left 45 plus people dead” (Blue Planet, 2017, table 1). Because of the abnormal warm sea surface temperatures, there were multiple shark attacks off the Oregon coast. This caused the sharks to migrate towards the warm ocean waters. The California coast suffered from continuous violent rain, wind and high tides that eroded the shore. The erosion caused fishermen to notice different species along the coastline that did not belong in that particular area (Gannon, 1986). Also during the famous 1982-1983 El Niño, Hawaii was hit by Hurricane Iwa causing an abundance amount of damage (Blue Planet, 2017). “Perhaps one of the most striking effect of the 1982-1983 El Niño was recorded by David Salstein and Richard Rosten of Atmospheric and Environmental Research, Inc. in Cambridge, Massachusetts. They found that the angular momentum of the Earth shifted slightly as a result of changes in the normal pattern of the jet stream and trade winds. In late January, at El Niño’s peak, the

Nature Magazine said, “Others have talked about the potential that summer sea ice melt and increasingly open waters in the Artic Ocean might be altering the flow of the jet stream that circles the Northern Hemisphere (Nature Magazine).” This was a more complicated to wrap your head around, but it also makes sense that something would also be going on in the water to cause these storms such as Hurricane Sandy or Hurricane Katrina. In the article it also states on this subject that this could be responsible for the reason Hurricane Sandy hit and for many of our past large winter storms as

Hurricanes occur more often on the East coast (Atlantic Coast) and the Gulf of Mexico.

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

What causes El Nino: “Scientists do not yet understand in detail what triggers an El Nino cycle. Not all El Ninos are the same, nor do the atmosphere and ocean always follow the same patterns from one ElNino to another. There isn't one big cause, which is one of the reasons why we can't predict this thing perfectly,"

California feature is that it has almost all of climate types such as: windy, hot, cold, and etc. What’s the impact of climate variability and change? Well according to the (sciencedirect). There is increasing concern over the consequences of global warming for the food security and livings of the world's 36 million fisher folk and the nearly 1.5 billion consumers who rely on fish for more than 20% of their dietary animal protein. With mounting evidence of the impacts of climate variability and change on aquatic ecosystems, the resulting impacts on fisheries livings are likely to be significant, but remain a neglected area in climate adaptation policy. Drawing upon our research and the available literature,

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

Warm water is crucial thus why we only see hurricanes in tropical regions that are close to the Equator.

You're probably thinking about how did El Nino gets it’s name it mean a boy which really means baby Jesus. So that make El nino a spanish word . El Niño is Spanish for Jesus. El Nino cycle starts by 1. During normal weather , Trade winds starts to blowing towards asia. 2.the trade winds week in and gets cold and move eastern of south america. El nino can affect weather in other parts or half of the world.
