Table 11. Results of analysis of variance (ANOVA) of wind speed at the Klamath Falls Airport and at the Bureau of Reclamation Agrimet site located at Agency Lake, Oregon, July and August, 1990–2004.

[Medians were calculated from hourly values obtained from the National Climatic Data Center (NCDC) 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. Medians at the Agency Lake Agrimet site were calculated from hourly values that fell in the upper one-half of the distribution for the month, as determined by combining 5 years of the record from 2000 to 2004. 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]
