ENSO El Niño Southern Oscillation Pages

EL NINO Go to this website and read this background information first: htmlhttp://oceanservice.noaa.gov/facts/ninonina. html You may need to come back to this website to fill in any notes that you missed

El Nino current in S. hemisphere  Ocean currents reverses  Warm water pools near S.America  Cool water pools near Australia

Global Effects of El Nino  S. America- more rain; warmer  Floods/mudslides  Australia- dry; cooler  Less typhoons

El Nino’s effect on the United States  Warmer winters/ drier in N states Wet/colder  Wet/colder winters in S states

Chris Farley is El Nino

“LA NINA”  Cool phase of ENSO (neg. phase)  Trade winds intensify

La Nina

South America- drier/colder Australia- wetter/warmer N. US- Colder than normal winters »Increased snowfall S. US- warmer/drier La Nina’s effects

El Nino or La Nina?

winter forecast
