A jet flow was used to model roughly a localized region of atmospheric turbulence, simulating a single idealized “eddy.” The jet was arranged in the UTIAS 80‐ft sonic‐boom generator horn so as to blow either against or with the direction of boom propagation. The two cases produced spiked and rounded boom signatures, respectively, qualitatively in accord with theory. The resemblance to signatures resulting from supersonic flight under turbulent atmospheric conditions was especially marked with the spiked “superbooms.”
