| VonKarman Vortices; Canary Islands, Atlantic. This fluid-flow phenomenon around solid objects, from butterfly wings to airplane wings to islands, is easily seen leeward of the Canary Islands. This pattern indicates that the winds are in the range of 5 to 13 meter/sec and the inversion layer is below the island mountain peaks. When wind speeds are greater, cloud eddies are elongated or pulled apart to some degree. Studies of natural Von Karman vortices provide insights for modeling air-flow patterns around aircraft - e.g., interactions of vortices from planes flying in close formation and comparisons of vortices from aircraft vs. those from mountain peaks. |
