1) Some Considerations on Combination of (Rain) Bullets which have the Axial Angle between the c-Axes of 90°
by Hiroshi Uyeda and Katsuhiro Kikuchi
From the Journal of the Faculty of Science, Hokkaido University Series VII (Geophysics), Vol. 7, No. 2
Sapporo, Japan February 1982
Abstract
The arrangement of the a-axes and the c-axes of a combination of bullets in which the axial angle between the c-axes of the neighbouring two bullets was approximately 90° was examined.
Samples examined were replicas of snow
crystals collected by Kikuchi during over wintering from 1968 to 1969 at Syowa
Station, Antarctica.
In thirteen clear replicas of the examined samples, one of
the a-axis of a bullet constituting a combination of bullets was in parallel to the c-axis of the another bullet when the axial angle between the neighbouring two
bullets was about 90°.
In two samples which were composed of more than four
bullets, a pair of prism planes of two bullets whose axial angle was approximately 90° was almost in parallel with each other.
The axial angle between the c-axes of about 90° of a combination of bullets was explained by the combination of the c-axes constructed by the repetition of the formation of cubic structure on a basal plane. Further, the arrangement of the a-axes was determined with the same model.
A possible three dimensional con-
figuration of combination of bullets in snow crystals was considered.

2) Measurements of the Principal Axis of Frozen Hemispheric Water Droplets
By Hiroshi Uyeda and Katsuhiro Kikuchi
From The Journal Of The Meteorological Society Of Japan
Vol. 58, No. 1, February 28, 1980
Abstract
Freezing experiments on supercooled hemispheric water drops of an approx in diameter were carried out from a point of view of the formation mechanisms of the origin of polyerystallization of frozen cloud droplets. Hemispheric water droplets were seeded with a basal plane and a prism plane of single crystalline ice-needle type in the u with ranges of -17 to - 20°C, - 20 to -23° water -rops - °C, respectively.
Notable polycrystallization occurred when hemispheric water drops were seeded with basal planes of …(see pictures)

3) The Size Distribution of Cumulus Clouds as a Function of Cloud Amount
By Kunihiko Hozumi, Toshio Harimaya and Choji Magono From The Journal Of The Meteorological Society Of Japan
Vol. 60, No. 2, April 28, 1982
Abstract
Small cumulus clouds over the ocean were observed photographically using air liners in the periods of AMTEX
'74 and '75. These photographs were analyzed to determine the
size distributions of cumulus clouds as a function of cloud amount by the trigonometric method. It was found that the size distributions are represented by the exponential distribution N=a-exp(-bD), where N is the number concentration and D is the diameter. The coefficients a and b are expressed exponentially as functions of cloud amount.
The flatness of convective cells were also analyzed. It was shown that the cell diameter has a linear relation to its depth, and that the cell flatness has a linear relation to the reciprocal of its depth.
