内容記述 |
The horizontal and vertical falling motions of snowflakes were imaged by two CCD cameras. These images were analyzed by an image processor and a computer. The size and position of each snowflake were measured every 1/30 s from their two images. There were three patterns in falling motion of snowflakes : rotational motion, swing motion and straight motion. The angular velocity of smaller radii of rotational motion was faster than that of larger ones. On the other hand, the radius of rotational motion didn't depend on snowflake size. |
