结果表明，当降水事件的空间尺度发生变化时，区域平均降水时间序列的长期平均强度和感兴趣区域内各点的长期平均强度会发生不同的相对变化。当试图从气候模式模拟的区域平均格箱降水统计数据中推导出细尺度气候变化情景时，这种影响是有问题的。这种影响的例子给出了使用模式预测的变化强度和变化的降水类型（天气或对流）。
It is demonstrated that the long‐term‐mean intensity of an area‐mean precipitation timeseries and the long‐term‐mean intensities at the points within the area of interest can change by different relative amounts if the spatial scale of precipitation events changes. This effect is problematic when trying to derive fine‐scale climate change scenarios from the statistics of area‐mean grid‐box precipitation simulated by climate models. Examples of this effect are given using model predictions of changing intensity and changing precipitation type (synoptic or convective).
