On the Persistence of Rising or Falling of Dayly Mean Air-temperature

Abstract

The frequency (denoted by Nn) of the case that dayly mean air-temperature had lasted n days to rise was found statistically to be represented well by the formula, here A and α being constants to be determined from the data of observation. As to the case of falling of the temperature, the same formula was obtained. The author used the data of the observations at Kyôto and at Yagi.
