'Ship Trails' Cloud Structure
But to the brightest beams
Distracted clouds give way...
William Shakespeare, Alls Well That Ends Well, Act V, Scene III
The dimension of such cloud lines reaches as much as 30
km width (sometimes up to 50 km) and up to 1000 km (and more) length.
It is supposed that this structure has an artificial origin,
because it is connected with the navigation of vessels.
The "Ship trails" cloud structure can be observed mostly over North Pacific (close to the west coast of the USA, Aleuts, Kamchatka and northeast coast of Japan) as well as over North Atlantic (west coast of Europe, east coast of Newfoundland), rarely - not far from the Peruvian and Chile coast, coast of Namibia, Tasman Sea.
