| NASA DATA INDICATES EL NINO WILL INTENSIFY AND MOVE EAST | G03-001 | 12/12/02 | 00:03:40 | Historically, El Nino's effects on the United States weather are greatest when El Nino's warm waters encroach on the coast of South America.

TAPE CONTENTS: |
| ITEM (1): Satellites Monitor Warming in the Central Pacific - Satellite data shows that warmer than normal waters are in the central Pacific Ocean unlike the last El Nino. During 1997-1998 El Nino, waters warmer than average were right up against the South American coast. Historically, El Nino's effects on United States weather are greatest when the warm waters are nearing the coast of South America. The moderate resolution imaging spectrometer (MODIS) aboard the terra satellite provided the data for this sea surface temperature anomaly animation from June to November. It shows that El Nino's warmest waters, reflected in yellows and reds, are concentrated in the middle of the equatorial Pacific Ocean throughout the fall.

| ITEM (2): Climate Models Indicate El Nino Will Move East - NASA's seasonal to Interannual Prediction Project climate model (NSIPP) predicts that the El Nino will get a bit stronger and extend to the east. This image starts with the January 15, 2002 climate model. Then it goes into the sea surface temperature anomalies from June to November 2002 and dissolves into the January 15, 2003 model. NSIPP shows a slight intensification of the warmer than normal pacific waters in January. In the past, El Nino's impact on U.S. weather was strongest from mid-January to early spring.

| ITEM (3): Monitoring El Nino From Space - New NASA satellites like terra are providing data with higher accuracy and resolution than five years ago during the last El Nino. This data is essential for helping scientist gain a better understanding of how El Nino evolves which could lead to better El Nino predictions.
