JOURNAL FREE ACCESSStructures of wind and air temperature fields in the lowest air layers were presented in terms of power and cross spectra, which cover the frequency range from 0.02 to 1 cycle sec-1. Owing to the lack of stability of the spectral estimates in low frequencies, an analysis of the spectrum was chiefly centrated in the range of high frequency, where an existence of the local isotropy might be expected. The lower isotropic limit in frequency, and dimensionless constants in one-dimensional energy spectrum and the structure function were obtained. They were of the same order of magnitude with those obtained by other investigators. Some notes on cross spectrum and coherence between two turbulent fluctuations were made.View full abstractDownload PDF (1084K) -
Choji Magono, Katsuhiro Kikuchi1963 Volume 41 Issue 5 Pages 270-277

JOURNAL FREE ACCESSCharges on artificially melted snow crystals were measured and compared with those of unmelted crystals which fell at Mt. Teine, and it was found that the snow crystals acquired considerable positive charge in their melting process. The result of this observation appears to explain the usual phenomenon that in continuous rainfall the negative surface electric field is predominant and most of raindrops are charged positively while in quiet snowfall positive field is predominant and snow crystals carry negative charge in most cases.View full abstractDownload PDF (1032K) -
Takio Suda1963 Volume 41 Issue 5 Pages 278-287
Published: December 28, 1963
Released on J-STAGE: October 19, 2007
JOURNAL FREE ACCESSAs a sequel of the author's previous paper on the diurnal variation of upper wind, wind data at 4km level over Japan were analyzed and it was found that the diurnal rotation of upper wind vector is systematic both in latitudinal and seasonal change, and closely related with the seasonal variation of solar declination.
The diurnal variation of typhoon movement was detected, as is the case with upper wind. Also the correlation of diurnal amplitude of typhoon movement with sunspot number was investigated and some positive correlation was found.
It was concluded, as the result, that the diurnal variation of typhoon may be caused by that of upper wind.View full abstractDownload PDF (971K) -

JOURNAL FREE ACCESSErrors in numerical analysis using three observing stations are discussed for the large and small scale network. First, the differences between flux and advective form calculation are verified to be sufficiently small. Second, the errors caused by the drifting of balloons are shown to be considerably large in the smaller network.View full abstractDownload PDF (250K) -
