On the Variation of Wind Velocity near the ground as observed with pilot balloons

[摘要] The author draws attention on the peculiarty of the variation of wind velocity near the ground measured at Kobe with pilot balloon, as shown in the table in p. 00. The velocity measured a little above the ground is smaller than that measured at the ground. The observatory stands on a hill. The stream lines most closely assemble at the hill top. The author left the problem. unsolved but his opinion is that the above peculiarity must due either to the stream effect or to the instrumental error of anemometer at the ground.
