El Nino and La Nina Webquest
El 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 impacts include drought conditions, warmer or cooler than normal temperatures for different areas, precipitation pattern changes, an many other impacts which could all pose a threat for agriculture , animal and human health, and plant life.
La Nina is essentially the opposite of El Nino so it is a reduction in ocean temperatures which can cause drought. After a El Nino a La Nina typically occurs so areas will be flooded and then a year later be in drought conditions.
How do scientists study el nino and La nina
Scientist study a variety of tools an techniques to monitor and forecast changes in the Pacific Ocean and the impact of those changes on global weather patterns.
El Nino and La Nina can by detected using many methods such as:
-sea level analysis
Social and Economic Effects
fires droughts Temperature changes precipitation changes
impact it has on our climate
Can cause heavy rain, flooding and fires
predicting el nino and la nino
help countries with their strategic planning to ensure security in areas such as agriculture, fishing, water resource management, flood control and energy supply, thereby reducing the vulnerability of the people and country.
