>Equatorial Currents Before, During, and After The 1997/98 El Nino

Posted on February 16, 2009 by Bob Tisdale

>INTRODUCTION Most discussions of El Nino events center primarily on Sea Surface Temperature anomalies. Sometimes they include descriptions of surface (trade) winds. Rarely do they include illustrations of surface currents, but the changes in surface currents are a significant part … Continue reading →
