Because of the high population density and topographical characteristics of the many mountainous regions in the Republic of Korea, the buildings are constructed not only on flat land, but also on relatively flat terrain between slopes and mountains. The wind speed may increase between these mountains owing to the convergence effect, which is called the funnel effect. Because the funnel effect between mountains is difficult to assess quantitatively, it is evaluated by reproducing the mountain range in wind tunnel tests. In this study, the wind speed amplification factor was calculated according to the gradient (0.3, 0.4 ,0.5, 0.6) of the mountain and the distance(1 to 5 times the height of the mountain) between the mountains based on the idealized 2-dimensional mountain, and an empirical formula was derived. The higher the gradient of the mountain and the smaller the distance, the greater wind speed amplification factor, and the maximum was about 1.12. An empirical formula to which this trend was applied was derived. Additional wind tunnel tests were conducted to verify the empirical formula, and the test data and the data calculated by the empirical formula were compared. As a result, the error rate of the empirical formula was about 2%. If the empirical formula is used in a case similar to the topography conducted in this study, it is expected that the funnel effect can be predicted more quantitatively.
