The El Niño of 2002-2003

1. Evolution of zonal wind, SST and 20°C depth along the equator (TAO):  Values       Anomalies
2. Compare 1991 vs 2002:  Observations   Anomalies
            Same for 1994-95: Anomalies
            Time series, smoothed and unsmoothed

3. Wind features during 2002.
   These are QuikSCAT weekly winds from CERSAT. Anomalies here are either from the 1991-2001 ERS climatology, or from the 1961-1997 FSU climatology. Neither is perfect (what is a perfect climatology anyway?).
   1. Curl climatologies:   ERS (1991-2001)       FSU (1961-1997)
   2. 12-months of QuikSCAT curl (maps):  Values      Anomalies (ERS)       Anomalies (FSU)
   3. 4 seasons of QuikSCAT curl anomalies (maps):  ERS       FSU
   4. Tau seasonal components:  Tau-x values      Tau-x anomalies      Tau-y anomalies      Vector anomalies
   5. Time series (x,t) comparing TAO Z20:   5°S      5°N     (slant lines show Rossby wave speed (0.8 m/s))

4. 2002-03 had no warm SST anomalies at S. America during its peak!:
   1. Maximum SSTs during various El Niños: 1991-2003   1980-2003
