TANSO-CAI observed Karman cloud vortices around Guadalupe Island in Mexico, Jeju Island, and Yakushima Island.
The Karman vortex street is a repeating pattern of swirling vortices behind an object disturbed the fluid flow.
Figure 1 shows the Karman vortices off Guadalupe Island, Mexico observed by TANSO-CAI, on June 27, 2018. Guadalupe Island is located inside the red box in Fig. 1 and an enlarged image is shown in Fig. 2. A signature cloud vortex repeatedly appeared in the south of Guadalupe Island.
Figure 3 shows a formation of the Karman vortices around Jeju Island and Yakushima Island, on October 30, 2017.
As described above, the Karman vortices form everywhere while satisfying all the conditions of obstacle mountain height, cloud and wind.
※The TANSO-CAI image was composed of band2 (674nm) in red, band3 (870nm) in green and band1 (380nm) in blue.
