On Numerical Prediction (III)

[摘要] In this paper the prediction of the spatial correlation coefficient and the time correlation coefficient of the atmospheric disturbances has been discussed in connection with the distribution function of the fluctuations in pressure patterns. In the case of wind-tunnel turbulence, the spatial correlation coefficients are easily trans-formed to the time correlation coefficients, since the time coordinate t is transformed to the space coordinate x, multiplying the general flow U by t. In the case of atmospheric disturbances, however, the transformation is not uniquely determined and hence there occurs an apparent difference between the spatial and time correlation coefficients.
