Title: Leaf motion in still air in ON
Answered by: Anne Bossart

QUESTION:

What causes a tree or plant to dance when the other plants around it are still and no wind???

ANSWER:

Seeing a plant or tree "do" that is one of the things that brings back a childhood "sense of wonder" and a reminder of the almost magical mysteries of nature, doesn't it?  Hearing the rustle of poplar leaves on a day when there seems to be no breeze whatsoever is one of my favourite examples.

Although the air seems still, it isn't actually.  There are many factors like differential heating and cooling and structures that cause the air currents to eddy and vary in speed in different locations that are in close proximity.  Once the air catches the plant it can set it into a state of motion that is similar to a standing wave which will linger after the gust of air has subsided.

Of course that is just one explanation and a dry, scientific one at that.  Personally, I like to savour the more magical side of nature (and summer) whenever I have the chance.
