Abstract or Summary
  • Sixteen propeller anemometers were placed 29 meters above a 45-year-old (approximately) Douglas-fir stand. Correlations between paired anemometers, when viewed as a function of distance between them, showed that eddies up to 5 meters in diameter were common, and indicated that larger eddies up to 9 meters across occur. Partial correlation coefficients between anemometers indicated that eddies are simply connected in cross section. Morning and nighttime data were excluded from analysis because the air was too calm. Results are related to the use of the eddy correlation method of determining atmospheric fluxes and the lack of preferential locations for updrafts or downdrafts above a tree crown.
