摘要
This study reveals the physical backgrounds of the geometric centroid and the thermal centroid of the Western Pacific Warm Pool (WPWP) and points out their differences. The geometric centroid (actually a very close approximation to the mass centroid) anomaly of the surface WPWP correlates more closely with the Nino-3 region sea surface temperature anomaly (Nino-3 SSTA, an important indicator of El Nino/La Nina events) than the surface thermal centroid. Taking the WPWP depth (or heat storage) into account, the "real" mass or thermal centroid of the WPWP might correlate better with the El Nino/Southern Oscillation (ENSO) signals.
