El Nino/La Nina
By: Morgan Avent
El Nino and La Nino are examples of short term climate change.
El Nino is a period of ocean warming that affects global weather patterns. El Niño impacts include drought conditions, warmer or cooler than normal temperatures for different areas, precipitation pattern changes, and many other impacts which could all pose a threat for agriculture, animal and human health, and plant life.
La Nino is the abnormal warming of surface ocean waters in the eastern tropical Pacific and it affects areas all over the world through the warming of the pacific ocean. El Nino are torrential rain, flooding, and mudslides to coastal areas of Peru and Ecuador which are usually dry, and severe drought to Indonesia and northern Australia during monsoon season. El Nino only occurs once every 7 to 14 years and effects weather patterns over most of the earth.
La Nina is essentially the opposite of El Nino so it is a reduction in ocean temperatures which can cause droughts. Typically after an El Nino a La Nina will occur so areas will be flooded and then a year later be in drought conditions.
Scientists study these phenomena by using a variety of tools and techniques to monitor an forecast changes.
El Nino is detected by many methods, including satellites, moored buoys, drifting buoys, a couple of there tools.
The opposite climates variations are social and economic effects of El Nino and La Nina.
A benefits of being able to predict El Nino and La Nina is so that we can prepare from the disastrous effects.
Some impacts on these phenomena haveing on our climate and weather are severe weather.
