From the results of our studies on outdoor conditions-temperature, solar radiation, absolute humidity and wind-on the hottest days that were the maximum air temperature of the year, it is found that outdoor air temperature and solar radiation are mutually related but both absolute humidity and wind have little correlation to the other conditions, so that they may be treated upon their own standpoints. In this paper we deal with the wind during the cold period by means of statistical treatment in the same ways as our precedent papers. The results having much significance are: (1) Throught the year, wind velocity is large in daytime and is more remarkable in summer than winter, and just before every sunrise it is weakest. (2) The mean value of wind velocity of every day is sure to be about 2.6m/s during summer season. And the frequencies of calm (less than 0.5m/s) are are only about 2 percent, but in Osaka they are higher, during nighttime, than in Tokyo. (3) The main wind direction in summer days are turned out to be southern in Tokyo and western in Osaka, and 70〜80 percent of them are more than 3.4m/s.
