Abstract: By means of a vertically pointing pulsed-doppler radar, observations were made of a growing thunderstorm moving overhead. An updraft having a maximum speed exceeding 19 m sec?1 was observed in the upper part of the cloud. ...

Abstract: Observations of Doppler spectra from particles 610 m above the ground were obtained by means of a vertically pointing X-band radar during a period when large hail was falling at the ground. It was found that the variance ...

Abstract: An X-band pulsed-Doppler radar having its beam fixed at an elevation angle of 3°, has supplied new data on radial velocity spectra in two showers. It was found that the mean Doppler velocity, variance of the Doppler spectrum, ...

Abstract: Observations were made of the depolarization of 3-cm radar signals by hydrometeors in a thunderstorm. Observations of backscattered power and Doppler spectra were made at the same time. It was found that depolarizations ...

Abstract: Observations of a thunderstorm by means of a vertically pointing pulsed-Doppler radar were used to compare two presently used schemes for estimating vertical air velocity in convective clouds. It was found that the air ...
