Comparing the 1998-1999 La Nina event to the corresponding 2006 Sea Surface Temperature Anomaly Conditions
|
Are we seeing another La Nina event in 2006? This animation compares the winter 1998-1999 La Nina event to the corresponding 2006 conditions in the Pacific Ocean. This is done by comparing Sea Surface Temperature (SST) anomalies (i.e., differences from normal SST values) between 1999 and 2006. Blue areas indicate ocean regions 5 degrees Celsius (9 degrees Fahrenheit) cooler than the norm. During the 1998-1999 La Nina event this resulted in a distinct area of deep blue stretching across the Pacific Ocean. Through this comparison, one can see that our current ocean temperature conditions do not reflect those same conditions during the 1998-1999 La Nina event.
