What’s a phenomena? zAn event that impresses one as out of the ordinary; sometimes unexplainable Elementary my dear Watson? Sherlock Holmes

Strange phenomenon occur during an El Nino and La Nina like...

Brush fires caused by drought

Increased Tropical Storms

Hurricane Floyd was HUGE!

Causing devastating floods in NC, 1999

Peruvian anchovy populations declined

Before After Regions of the US Pacific coast were severely changed due to heavy rains and flooding

What causes an El Ni n o?

Sea surface anomalies associated with El Nino

SST differences between El Nino and La Nina

A B C QUIZ! Which is which… Normal, El Nino, La Nina?

Were you’re predictions correct?

How can we predict an El Nino or La Nina event?

Need measurements to make predictions

NOAA drifting buoys Measures... ztemperature zcurrents zwinds

Satellites

TOPEX/Poseidon (T/P)

TOPEX/Poseidon (T/P) helps predict El Nino and La Nina
