Most of the time, temperatures for all stations were within + °F (2 °C) of station 2. During February, maximum temperatures of a few stations ex- ceeded these limits. When minimum temperatures fell below the limits established, more stations exceeded the lower limit. December 12 and 20 in figure 6 are typical examples. Cold air drainage at these times established a stronger temperature gra- dient from warm ridgetops to the cold valley floor of the main stream channel. Tempera

Cold air drainage at these times established a stronger temperature gra- dient from warm ridgetops to the cold valley floor of the main stream channel. Temperature gradients within the area were generally quite low. Mean daily temperatures were also computed for all data (on an hourly basis) for the winters of 1976-79. This temperature chronology is presented in the appendix. The 1977-78 winter temperatures were the mildest, and the 1978-79 winter appeared to have the longest and most severe periods of cold weather. Wind.—Wind-measuring equipment allowed separation of data into windspeed classes. Summary information for total travel of wind at the measuring stations for the winters of 1976-77 is presented in figure 7, on the basis of all wind observed greater than 5 m/h. The effect of topography on the pattern of the isograms in this figure is well defined. As expected, exposed stations had consistently greater wind Figure 7—Total windflow (miles X 1000) at windspeeds of 5 m/h or more. 9.
