On the Density of Snow on the Ground

[摘要] On January 30th snow fell in Tokyo nearly all day long. The author measured the density of snow on the ground while snow was still falling. The result of his measurements is depth of snow from its surface 2.5 7.5 10 12.5 15 20 24cm density 0.033 0.065 0.074 0.080 0.081 0.081 0.084These values are very near but a little less than those for new snow, given by K. Abe at Sapporo and nearly 1/3 of those for old snow given by T. Okada and by K. Abe in Hokkaido. The author believes that an exponential law hold good hetween the density and depth.
