Abstract
We analysed fifty-three microbarometric waves (period 5 min.-40 min.) observed at Tokyo in 1933 by the statoscopes and the Yosida's microbarograph at five different places.
Most waves are found to be progressive like three examples reported by Messrs. T. Kita and H. Huzita last year.
In addition, the waves seem to be topographically conditioned, since the direction of their propagation is almost to N, NE or to E., and some waves have local natura. Moreover, their propagating velocities (ca 0.2km/min to ca 4.0km/min) diminish as they advance.
Daily changes of the wave occurrence are shown in § 5.
