这项研究在5-60分钟的时间尺度上考察了温和地形下的夜间温度变化。这种温度变化在傍晚快速冷却后通常是重要的,并可能导致大的暂时变暖或增强冷却。本文用一个平缓地形上的通量站网统计检验了温度变化的时空结构。大的温度变化往往与相干传播模式和相关的暂时减少或消除山谷冷池,局部排水流,背风湍流。最大的温度随时间的变化发生在中等风速。低风速对应于更大的温度空间变异性,但时间依赖性较小。两个无量纲的比率来表示时间和空间变异的相对重要性。
This study examines nocturnal temperature changes on time‐scales of 5–60 min over gentle terrain. Such temperature variations are often important after the early evening period of rapid cooling and can lead to large temporary warming or enhanced cooling. The time–space structure of temperature changes is examined statistically with a network of flux stations over gentle topography. Large temperature changes are often associated with coherent propagating modes and associated temporary reduction or elimination of the valley cold pool, local drainage flows, and lee turbulence. The largest variations of temperature with time occur for intermediate wind speeds. Low wind speeds correspond to greater spatial variability of temperature but less time dependence. Two nondimensional ratios are developed to represent the relative importance of temporal and spatial variability.
