作者在具有大型阶梯屋顶花园的建筑周围进行了三次小气候的实地测量。本文主要介绍了最近一次长时间的测量结果，目的是掌握夜间重力流在绿坡边下游的发生情况。从这些测量中，得到以下结果。1. 在风平浪静的夜晚，绿坡底部出现了断断续续的下游，湍流较小。下游的时间大约是20到80分钟。2. 绿坡底部下游最大风速约为0.5 m / s，绿坡顶部和底部的最大温差约为1度。3. 通过风向、风速和屋顶净辐射进行分类，明确了20种条件下下游的发生频率。
The authors performed the field measurements in the microclimate around the building that has the large stepped roof garden for three times. In this paper, the results of the last long time measurements are mainly presented, the aim of which is to grasp the occurrences of down stream along by the green slope due to the gravity flow at nighttime. From these measurements, following results are obtained. 1. In the calm night, the intermittent down stream with small turbulence was observed at the bottom of green slope. The duration of the down stream is about twenty to eighty minutes. 2. The maximum wind speed of down stream at the bottom of green slope is about 0.5 meter per second and the maximum difference of air temperature between the top and bottom of green slope is about 1 degree. 3. The frequency of the occurrences of down stream was clarified under the twenty conditions, which are classified by the wind direction, wind velocity and net radiation at the rooftop.
