In this paper we describe a wind tunnel invesitigation on the wall wind pressure on a tall model surface in a simulated atomospheric boundary layer. The influence of a low model placed upwind of the tall model was discussed in first paper. This time we plan to discuss the influences of the low models placed around the tall model shown in Fie. 3. Measurements are made of the influence of the height of the low models and distance of models. The results are expressed in the form of coefficient of wall wind pressure, normalized by means of dynamic pressure of free stream, and reduction ratio, normalized by means of wall wind pressure on surface of isolated model. The summary of the results is shown below. 1) The influences of the low models get bigger as the height of the low models get higher. 2) The influences of the low models get smaller as the distance of models get wider. 3) The maximum value of reduction ratio appears for value of d/h = 0.4〜1.5.
