为了评价在几个集中研究期间观测到的排水流量的代表性，对1982年8月至1985年1月期间刷溪山谷夜间排水流量的月频率进行了估计。这些估计是根据位于山谷中的三个短气象塔的数据作出的。在7月至10月的时间范围内观察到的频率最高：1983年为30%-40%，1984年为5%-25%。十个实验夜，当深入调查进行了刷溪山谷，七个是在强排水流量期间，三个是在较弱的排水流量期间。由于σ θ常用于估算污染物扩散，因此研究了复杂地形地区σθ的变化。在北方加州间歇泉地热区的两个山谷内和刷溪山谷内的强排水流期间进行的测量产生了平均小时数。
Abstract The monthly frequencies of nocturnal drainage flows in the Brush Creek Valley were estimated over the period August 1982–January 1985 for the purpose of evaluating the representativeness of the drainage flows observed during a few intensive study periods. These estimates were made on the basis of data from three short meteorological towers situated in the valley. The highest frequencies were observed during the July to October timeframes: 30%–40% during 1983 and 5%–25% during 1984. Of the ten experimental nights when intensive investigations were conducted within the Brush Creek Valley, seven were during strong drainage flow periods and three were during weaker drainage flow periods. The variability of a σθ in complex terrain areas was investigated since this parameter is often used to estimate diffusion of pollutants. Measurements made during strong drainage flow periods within two valleys in The Geysers geothermal area in northern California and within the Brush Creek Valley yielded median hour...
