Abstract
The vertical structure of the typhoon was investigated from the pilot-balloon observations.
A circular area of 1750km radius around the center of typhoon was taken as the domain of typhoon. This area was divided into 112 segments with six concentric circles and with sixteen radii. The results of observations in each segment were collected together and vectorial means of wind velocities, which were used for representing the mean state in that segment of the ordinary typhoon, were calculated.
Then the distribution of cyclonic winds was investigated, disregarding general currents. And the ascending or descending currents were calculated from the convergence or divergence of winds near the ground and at higher levels.
