•The Hilbert spectrum-based method and the two-dimensional (2D) indicial response function was introduced in the time domain buffeting analysis of a long-span bridge under nonsynoptic events.•The downburst wind presents significantly nonstationarity characterized by time-varying mean and spectrum, w...
