Abstract
This short note gives the results of investigation of miniature climate of the city of Tokyo using the data of meteorological observation made at the Central Meteorological Observatory, the Sinagawa Storm Signal Station of the C. M. O. and the Takinokawa Meteorological Station during the year 1937.
The results of investigation is that the town climate of Tokyo is not so remarkable as that of cities of European countries, but in winter night air temperature and humidity in and out of the town show great difference. This phenomena is rearkable since 1928.
The city influence upon the distribution of wind is very small, as that upon the distribution of air pressure. So the study of this problem must use precise instrument for wind measurement. But the present writer used the data measured by ordinary instrument as the first step of investigation, and the position of observation were central Tokyo, Sinagawa, Takinokawa and kotobasi.
The wind veiocity reduced at the layer of ten meters above the ground is greatest at Sinagawa and decreases in the order of Kotobasi, central Tokyo, and Takinokawa as the distance from the sea shore increases.
When southerly wind blows the velocity at Kotobasi is strongest, this is due to not only topography or no high buildings near the station but effect of the Bay of Tokyo.
