Generally El Nino and La Nina occur every 4 5 years. How La Nina Affects Weather and Climate Rain clouds form as a result of the lifting of warm moist air.

Admittedly it can cause some very unusual patterns and extreme results.

What causes el nino. El Ninos typically occur every 3 to 5 years. The other two parts being La Nina which is essentially the opposite of El Nino and neutral which is any time period when most climatic factors are relatively average. El Nino is a weather pattern.

The outcome of the eastward displacement of the atmospheric heat source lying on top of the warmest water is drastic change in the global wind cycle circulation. Warm water is pushed back east toward the west coast of the Americas. La Nina the cool phase of ENSO is a pattern that describes the unusual cooling of the regions surface waters.

In general El Nino causes vast amounts of rainfall in the eastern parts of the Pacific the western coast of South America and very dry weather on the western parts India Indonesia. El Nino is a climate cycle in the Pacific Ocean with a global impact on weather patterns. The cycle begins when warm water in the western tropical Pacific Ocean shifts eastward along the equator.

What causes El Nino and La Nina to occur. In El Nino years ocean waters along South America and California warm above normal temperatures. During this phase of ENSO the water is cooler than normal and the east winds are stronger.

For reasons scientists dont yet fully understand these relatively steady winds sometimes weaken or strengthen for weeks or months in a row. The opposite condition is called La Nina. An El Nino condition occurs when surface water in the equatorial Pacific becomes warmer than average and east winds blow weaker than normal.

A La Nina is actually beneficial for the Indian monsoon. The term El Nino basically means the child. During El Nino trade winds weaken.

The trade winds push warm water on the surface of the ocean from east to west westerly. To the east of the Pacific El Nino favors the increase of the chances of a hurricane due to the presence of warm air masses. Is the warm phase of the El NinoSouthern Oscillation ENSO and is associated with a band of warm ocean water that develops in the central and east-central equatorial Pacific between approximately the International Date Line and 120W including the area off the Pacific coast of South America.

El Nino is essentially caused by the interaction between the surface layers of the tropical Pacific Ocean and the atmosphere over it. Many rain clouds form over this warm part of the ocean and move inland dumping more rain than usual in South and Central America and in the United States. The winds near the surface in the tropical Pacific usually blow from east to west.

This is due to the fact that this current starts to flow around Christmas and hence the name referring to baby Christ. When the air doesnt get its warmth from the ocean the air above the ocean is abnormally cool above the eastern Pacific. El Nino events are actually just one halfthe warm wet halfof a naturally occurring weather cycle called the El Nino-Southern Oscillation or ENSO.

El Nino occurs when temperatures in the Pacific Ocean rise due to a change in the normal wind direction which causes extreme weather patterns across the world. El Nino is more frequent than La Nina. This leads to storms and cyclones in some areas while others are affected by droughts.

El Nino means Little Boy or Christ Child in Spanish. El Nino and La Nina are considered the ocean part of ENSO while the Southern Oscillation is its atmospheric changes. South American fishermen first noticed periods of unusually warm water in the Pacific Ocean in the 1600s.

El Nino affects the global climate and causes disruption in regular weather patterns. Another natural phenomenon similar to El Nino is the La Nina which is also in news these days. El Nino is a Spanish word.

Discuss the causes of El-Nino. La Nina causes drought in Peru and Ecuador heavy floods in Australia high temperatures in Western Pacific Indian Ocean off the Somalian coast and good monsoon rains in India. El Nino ɛ l ˈ n iː n.

This causes the warm water to build up on the western side of the ocean near AsiaMeanwhile on the eastern side of the ocean near Central and South America cold waters are pushed up towards the surface. Weak winds allow warm surface waters to build up in the eastern Pacific. In other words El Nino is caused by the weakening of the trade winds which results in pushing of warm surface water to the west and less cold water to the east.

It is one component of a recurring climate pattern known as ENSO El Nino-Southern Oscillation. With all the extra heat at the surface of the Pacific Ocean energy is released into the atmosphere causing an overall warming of the global climate temporarily. El Nino is the warm phase of a larger phenomenon called the El Nino-Southern Oscillation ENSO.

This prevents the formation of rain often needed in these areas of the world. The water is warmer due to the trade winds reversing direction.
