Correlation of Wind Records and Proxy Wind History from Tree Rings at Port Angeles, Washington with Sodium Concentration at Summit, Greenland, and Linkages with Gulf of Alaska Sea Level Pressure Forcing
Abstract:This analysis applies the experimental and theoretical understanding of tree growth structure from Telewski (1995) and Mattheck (1998) by quantifying instrumentally calibrated wind influence on development of interannual eccentricity variation in conifer growth. It explains Fritts' (1976) finding of covariance of interannual changes of tree growth in western North America with sea level pressure structure in the North Pacific Ocean in terms of local wind field changes in response to pressure field dynamics. After deriving seasonally synoptic wind relations, the association between growth eccentricity (and instrumental wind) and Gulf of Alaska sea level pressure is then used, along with Summit, Greenland sodium concentration data, to interpret steering of the western portion of the Kahl et al. (1997) winter, zonal aerosol trajectories at 700 and 500 hPa between the North Pacific and Summit.
