Jet stream drives summer temperature, plankton growth in Oregon mongabay.com August 6, 2007
John Bane, a North Carolina University research who was lead author of the paper, found that the north-south displacement of the jet stream along the Oregon Coast directly affect the upwelling strength during the summer. Analyzing wind, temperature, and biomass readings collected by ocean sensors over the summer of 2001, Yvette Spitz of Oregon State University led the development of a computer model that shows how shifts in the jet stream affect ocean upwelling and nutrient flow. Overall, the model suggests that when the jet stream is to the north, southward winds drive upwelling of cold, nutrient-rich water. A shift of the jet stream to the south, disrupts water upwelling and nutrient flow. CITATION: John M. Bane, Yvette H. Spitz, Ricardo M. Letelier, and William T. Peterson (2007).
