1)What can we learn about earth’s past through studying ice cores? 2) What can we learn about earth’s past through studying ocean sediments? Where do the conditions for El Niño develop? What are the “warm pool” and “cold tongue?” How do they change during El Niño conditions? La Niña conditions?
24 Two types of El Nino events are classified based on spatial patterns of the sea surface temperature (SST) anomaly(deviation from normal). Cold Tongue El Nino: Regarded as the conventional El Nino, characterized by large SST anomalies Warm Pool El Nino:associated with confined SST anomalies central pacific. Normal Conditions of Sea Surface Temperature: Western Warm Pool, Eastern Cold Tongue El nino: trade winds creates warm pool on eastern pacific and cold water on western pacific. La nina: Trade winds create warm pool on western pacific and cold water on the eastern pacific. (Regular conditions, just intensified) La nina is stronger trade winds. What conditions define an El Niño compared to neutral conditions? (in terms of sea surface temperature, thermocline position, productivity in the eastern Pacific, trade winds, and precipitation patterns) – make sure you refer to the geographic area you are talking about (i.e., the water gets warmer is not enough because some areas also get
