Table 9. Results of analysis of variance (ANOVA) of wind speed at the Klamath Falls Airport, Oregon, July and August, 1990–2004.
[Medians were calculated from hourly values obtained from the National Climatic Data Center after first selecting those that fell in the upper one-half of the distribution for the month, as determined by combining all 15 years of the record. Years that share a letter are not statistically distinguishable (p<0.05) from each other using this test. Years that do not share a letter are statistically distinguishable (p<0.05) using this test. Abbreviations: m/s, meter per second]
