A TUTORIAL ON BRIDGING GAPS BETWEEN LARGE SCALE CLIMATE AND LOCAL ENVIRONMENTAL PROCESSES
image
In this tutorial I provide an overview of large scale climate processes with an eye towards understanding local environmental changes that may be important to marine ecosystems. Large amplitude, highly predictable changes in the annual cycle are evident in nearly all measures of local and large scale environmental processes in the North Pacific. Smaller amplitude, mostly unpredictable variations around the mean annual cycle may also be related to large scale climate influences like El Nino Southern Oscillation, the Pacific Decadal Oscillation, or the Arctic Oscillation. I provide brief sketches of some of the ways in which these large scale modes of climate variability are expressed at local and regional scales with a focus on the nearshore Northeast Pacific Ocean. I will also review aspects of NE Pacific environmental changes of the past few years from local and large scale perspecitives.
