1) What is the El Niño Southern Oscillation (ENSO)? The combination of El Nino and the Southern Oscillation goes by the acronym ENSO. Southern Oscillation is an index which observes higher than average air pressure and the temperature between the ocean and atmosphere in the east central equatorial pacific. El Nino is the warming of the ocean surface. According to NOAA, during this time frame rainfall over Indonesia reduces while rainfall increases over the tropical Pacific Ocean. The combination
droughts. The Geographical Processes Involved The Geographical Processes Involved Causes El Nino El Nino is one of the main causes of droughts. An El Nino changes the relationships between the wind, ocean currents and atmospheric temperatures, which causes global impacts to weather conditions. Across the Pacific there Areas being affected by El Nino. is a mass of warm water that is driven towards Australia. This warm water leads heavy rainfall to the north of Australia
El Nino: Past, Present, and Future El Nino is both an atmospheric and oceanic phenomenon affecting weather patterns all around the world. It is complemented by La Nina in a cycle that occurs approximately every 4 years, varying as much as every two years to every six years (Wang 1999, 3331). La Nina has almost the opposite effect, however differs in its strength and duration randomly, as does El Nino (Fedorov 2000, 1998). The cycle is often paraphrased as ENSO, standing for El Nino-Southern Oscillation

El Nino We live on an incredibly large planet. Even broader than the size of the planet are the amount of changes and relationships between humans, animals, environment, weather, and the effects of each. Many times with busy schedules and modern lifestyles we forget the interaction that goes on between any number of concepts or ideas. We fail to realize that a specific weather occurrence in the Pacific Ocean can have an effect on every day life in the United States. El Nino is one of the largest
region. The most important climatic phenomenon that causes drought is Southern Oscillation. “Southern Oscillation is a primary air pressure change which is a seesawing of atmospheric pressure between an area just to the north of Australia and the central Pacific Ocean.” (Study Guide 23). It is also linked to El Nino and La Nina. “El Nino is a complex interaction between air and sea in tropical Pacific. “(Robert, 2013). El Nino means little boy in Spanish and also means unusually high atmospheric
El Nino This morning, before writing this essay, I spent a considerable amount of time watering my wilting garden. Meanwhile, the New York Yankees have been rained out for their third consecutive game. And out in California? Rain, no rain, rain, no rain... Why are we suffering such severe weather this summer? In case you have not heard, we are experiencing a weather phenomenon called El Nino. What is El Nino, and How Long Will This Last? According to Michael McPhaden, director of the Tropical

Valuable commercial sorts of fish usually dwelling in cold water will migrate from shores so New Zealand’s fishing industry is about to experience difficulties. More dryness and stronger wind on south island generated from El Nino phenomenon could lead to enormous wildfire and destroy huge amount of valuable
EL Nino is a climate cycle in the pacific ocean with a global impact on weather patterns. EL Nino occurs every 3-7 years. During an EL Nino event, the relationship between winds and ocean currents in the pacific ocean changes, modifying weather conditions around the world. I do have a few question. What are some differences between EL Nino and LA Nina? What relationship is there between EL Nino and North Atlantic hurricanes? LA Nina and North Atlantic hurricanes? EL Nino is a climate pattern that
cause drought, El Niño Southern oscillation, Indian Ocean dipole and variability and the Southern annular mode. Since drought in Australia can become so severe, the federal government has accepted drought as a feature of the climate and has emergency funding for those affected in times of ‘exceptional circumstances’ (textbook). With Australia being termed as the driest inhabited continent in the world drought can be broadly defined as a period of time
An El Nino event , the opposite of a La Niña, occurs when the Pacific Ocean and the atmosphere interact to create a ‘feedback loop’, exaggerating small changes in the state of the ocean, causing a deviation from its usual state (Kuhnel and Coates, 2000). These changes are usually driven by temperature gradients above and below the surface, specifically the thermocline (An analysis of the La Niña events in Australia, 2014). ENSOs generally begin during autumn in the southern hemisphere, strengthening
What are El Nino and La Nina? El Nino and La Nina are unusual weather patterns that form in the period of 10 months. El Nino and La Nina both impact climates all around the world, each different in countries and regions. Normal weather patterns are when low atmospheric pressure is over northern Australia and Indonesia, and when high atmospheric pressure is over the Pacific Ocean. Winds move east to west over the Pacific. The east flows of the trade winds carries the warm surface waters to the west
Residents of Southern or Coastal California may not realize the extensive issues that dry climate has caused on one of the state’s most profitable industries. Agriculture is not just a way of life in California’s Central Valley, it is the way of life for most, in some

The storm zone and atmospheric convection move with the warm water resulting in heavy rainfall and flooding along coastal areas of western

It is able to make half a world have wetter season and another be dryer than the dessert. This article talks about some fundamental observations, human history, and the impact and teleconnections that El niño has caused on today's
El Nino Typically, the level of ocean water around the world is higher in the western Pacific and lower in the eastern, near the Western coast of South and North America. This is due primarily to the presence of easterly winds in the Pacific, which drag the surface water westward and raise the thermocline relatively all the way up to the surface in the east and dampen it in the west. During El Nino conditions, however, the easterlies move east, reducing the continuing interaction between wind and
Ocean Contaminants and the Impact of El Nino The ocean is inhabited by many and loved by all. Whether you surf the waves or use it for recreational purposes, its important to us all. There are dangers to the ocean that anyone who bathes in it should be aware of. Besides the obvious dangers of the current and the pounding waves, there are possible microscopic enemies at large. Every year the beaches are closed for a variety of reasons. Sometimes it may be for a surfing contest, or if the waves
Parts of a Hurricane There are four major parts of a hurricane: the eye, eyewall, rain bands, and the outflow. The eye is the center of the hurricane. It is the calmest aspect of a hurricane because there are no high, damaging winds. In fact, the winds speeds are around 15mph. The eye is generally 20 to 40 miles across and is an important indicator about the formation of a hurricane because it is generally the most prominent aspect of a hurricane on radar and satellite images. In contrast, the eyewall
From 2005-2009, there were an average of 3,533 fatal unintentional drownings annually in the United States — about ten deaths per day. Most of these deaths were caused by swimming too far out in the ocean, getting picked by a large current, and then drowning. Water currents are perhaps the most important and influential natural activities that Mother Nature can produce. Over the years, currents have propelled ships across oceans, changed weather patterns around the world, and created ecosystems that
