Diffusion Experiments Using Balloons
摘要
Rubber balloons with cards, 48,900 in total, were released 16 times from 13 places in August 1960. The collected cards which informed the conditions of being captured and the states of balloons were 11,152. The data of 7 experiments which are suitable for detailed investigations were analysed. In these experiments, the diffusion phenomena up to 450km leeward were observed. Lateral standard deviations were calculated and parameters for lateral diffusion were determined. Examining these results together with those of other experiments, it is noticed remarkably that the parameters vary considerably in each experiment. This fact can be explained by the considerations that the diffusion phenomena depend upon the heights of layers where the phenomena take place. The detailed examinations show that the curves of standard deviations versus leeward distance have some peaks and valleys. It can be explained by the considerations made in the analyses of data of the Tokai experiments.
