The results of 8-hourly observations of radio sonde at Tokyo in one winter are used. By the characteristics of 8-hourly pressure variation in winter, the following facts are found. The troposphere is divided into three layers which are the 1 st layer from surface to 4km, the 2nd layer from 4km to 10km and the 3rd layer higher than 10km. The axis of pressure wave moving eastwards in winter, extends upwards with some inclination to rear side in 1 st layer, while the axis upwards vertically in 2nd layer. The height of 7km is the representative height of the 2nd layer for the pressure variation.
