 note = {Falling attitude of snowflakes were simultaneously photographed by two tv camerae from horizontal and vertical directions. These images were analyzed by image processor and personal computer. The attitude and location of each snowflakes were measured every 1/30 seconds from their two images. There were two patterns in falling motion of snowflakes, one was rotational trajectory, the other was spiral trajectry. And there was a tendency that the rotational speed of smaller snowflakes was faster than the bigger one, and the directions of revolution and rotation in falling snowflakes were the same in many cases.},
