In the gust response analysis for horizontally long structures on the frequency-domain, the spatial correlation of fluctuating lift forces plays an important role. Some recent researches have pointed out that the spatial correlation scale of the fluctuating lift force acting on bluff bodies is very larger than that of the fluctuating velocity of the approaching flow. To investigate the built-up process of the spatial correlation of fluctuating lift forces, the propagation of pulsasive disturbance generated artificially near the stagnation point of some thin plates was examined through the measurements of surface pressure. As a result of this study, it was clarified that the strength and the frequency of disturbance didn't affect the width and length of the area including the pressure fluictuation caused by the disturbance,and the width of the area propagating the disturbance change in proportion as the length of the separation bubble.
