Part I of this Seasonal Climate Summary present an analysis of the global climate during December 1992 - February 1993 (DJF). Atmospheric and oceanic indices indicate the redevelopment of mature El Nino-Southern Oscillation conditions in the tropical Pacific during DJF. This marks one of the longest periods of continuous warm episode conditions on record. Above normal sea surface temperature covered large portions of the tropical and subtropical eastern Pacific during the period. In the extratropics, one prominent feature during the season was extremely heavy precipitation totals over California and the southwestern US. This precipitation was associated with enhanced southwesterly flow, above normal cyclone activity, and enhanced transport of low-level moisture into the region from the subtropical North Pacific. A second prominent feature was a strong positive phase of the North Atlantic Oscillation.
