Modeling Investigation of Atmospheric Moisture Transport over the North Pacific Ocean: Role of Pacific Decadal Oscillation

Abstract

Atmospheric moisture content over the North Pacific Ocean can fluctuate under the influence of the Pacific Decadal Oscillation (PDO). For a better understanding of the role which the PDO plays in the North Pacific water budgets and pathways, we conducted sensitivity experiments to examine how atmospheric moisture transport responds to sea surface temperature (SST) anomalies associated with the PDO phases transitions.

This study has important implications for improving understanding of precipitation events in areas surrounding the North Pacific.
