In the past three days, the Keelung North Coast has seen unique 'flying saucer clouds,' which are circular cloud formations caused by strong southwest airflow passing over the Taipei Basin and forming on the windward slope in Keelung and the North Coast, resembling UFOs. Local fishermen and residents were amazed by this rare sight, with some speculating it might be related to typhoons or earthquakes, but the Keelung Meteorological Station clarified that it was a natural phenomenon devoid of such associations.
