 note = {We notice the fact that the number of atmospheric pulse per unit time at output of radio-receiver is closely related the thunderstorm activity. Then by use of this fact, we intend to find out some useful apparatus for predicting thunderstorms. From the results of several preliminary observations, we decide the tuned type lightning counter, which is adjusted to pick up lightning discharges within predetermined radius, to be one of useful auxiliary apparatus in our purpose. However, the tuned type lightning counter is not yet sufficient for forecasting thunderstorm. Because it indicate neither the direction of the occurrence district of storms nor the direction of storm movement. So as to supply these weak points, the apparatus combining the pulse counter and the uni-directional C. R. D. F. was designed.},
