On a Nomogram to estimate the Atmospheric Pressure in High Altitude from the Surface Observation and the Forecast of Upper Winds

[摘要] A nomogram was made which is useful for the estimation of the atmospheric pressure in high altitude from the surface observation, and it is found that the estimation can be made within the error of 0.5mm compared with the calculated value. Next, a scale was made which is used for the estimation of wind velceity from isobar, assuming the gradient wind. And these two were applied for the forecast of upper winds and the satisfactory results were obtained.
