Temperature distributions on the northeastern slope in the Konosu Experiment Farm, which is very gently sloping, were investigated during the winter of 1948-49. Results obtained on the fine day were as follows:
1. The diurnal movement of temperature stratifications along the slope is shown in Fig. 1. Outgoing radiation from the soil in the evening took place first at the slope and therefore warm air masses were recognized above it. The cold air from the heigh ground flowed into the lower places by night and accumulated on the concave field as well as in front of buildings, and this is confirmed by Fig. 3, which shows horizontal distributions above the slope 2. The minimum temperature distribution at the height of 10cm above the ground was different from that at the height of 1 or 1.5m. These distributions are represented in Fig. 2.
