A recent posting showed a few characteristics of fog: fog wave. However, fog offers a far richer variety of features than those I showed there. Here is one more: fog drops that have collected on a spider’s web.
Similar pictures offered on the web are almost always described as being dew drops on a spider’s web. This is patent nonsense. For dew to condense on an object, there must be a marked temperature difference between that object and the air. The thread of a spider’s web is much too narrow to sustain such a temperature difference. Dew does not form on a web.
However, as a collection net for fog drops drifting past, a spider’s web is superb. While large obstacles distort the movement of the air flowing past them so that the fog drops are merely carried around them, the threads of a spider’s web are so tiny that they intersect and collect the fog drops.
