Experiment is performed in windchannel with floor covered by series of street canyons.The passage of sweep and ejection events is detected as being long-term signature in lower frequencies. The passage of vortex is recognizable as circular patterns in higher frequencies on Wavelet spectrum.When using velocity vectors as input data, proper orthogonal decomposition (POD) reveals the most dominant modes in terms of turbulent kinetic energy.
