For further interpretation of the features of wind dynamic effects on hyperbolic cooling towers (HCTs), the dynamic responses were calculated and the features were analyzed.The analysis focused on the background component σ_B and resonance components σ_R, and their contributions to the total gust response σ.Then, the parameters of damping ratio ζ, velocity V and meridian correlation coefficient ρ were altered respectively to study their influences on the gust responses and the influence mechanism.It is shown that the coupling effects of σ_ and σ_R could be neglected for all responses.The contribution of σ_R to σ varies with responses and locations.If σ_R is neglected, the σ of F_X and F_Y decrease about 10% in the middle and bottom shell but about 20% in the top shell, and the σ of M_X decreases about 20%-30% for the whole shell height.With the increase of ζ, the σ_R  of all responses decreases remarkably and the decrease amount could be determined roughly by a simple equation.However, the decrease of σ is slight because the contribution of σ_R  to σ is limited, especially for F_X and F_Y.It is also found that σ_R is proportion to V3.The meridian correlation influences σ_B directly and then σ indirectly, so this influence is mainly on the σ_B of F_X and F_Y, which is predominant in σ.Nonetheless, σ_B of F_Y increases with the coefficient ρ, but σ_B of F_X decreases.Finally, in structural reinforcement designs, the resonance effects of meridian internal forces could be neglected and that of latitude internal forces couldn’t be neglected.
