Abstract
The Pacific decadal oscillation (PDO) is the target of ongoing research within the meteorological and climate dynamics communities, and is central to the work of many geologists, ecologists, natural resource managers, and social scientists. Research over the last decade has led to an emerging consensus regarding the physical processes that drive the PDO, including both remote tropical forcing and local atmosphere/ocean processes. PDO-related regional impacts should account for the effects of these different processes, which operate on different timescales and only partly represent direct forcing of the atmosphere by the North Pacific Ocean.
