Vector "surface" (e.g. 900mb), monthly (or seasonal) wind direction and velocity, early 20th century to present, at the northwest coast of Washington state, expressed as Rbar and Thetabar. I would need to know the composition of the data; how they can be related to hourly observations at 10deg. azimuth intervals.
Objective: Comparison of modeled wind with proxy wind direction and velocity derived from tree-ring eccentricity measured at and near weather stations having late 20th century surface and upper air records; using circular statistics after N.I.Fisher. This paleo-proxy research was reported in Transactions AGU 2002 Fall Meeting and is being extended in the upcoming IAWA-CIRAD October 2004 Symposium volume; the latter representing tree physiology investigators.
