The photo above shows Kelvin-Helmholtz wave clouds taken on January 5, 2022 near Taipei, Taiwan. From this vantage point on Datun Mountain, the wave structures were visible over the skyline for less than three minutes. A rare atmospheric phenomenon, Kelvin-Helmholtz wave clouds form between two air layers where there is a strong vertical wind shear and signal air turbulence in the lower atmosphere.
