Numerical Forecasting over the Far East by the Double Fourier Series Method

Abstract

The results of the numerical forecasting over the Far East is presented. In this paper, we use double Fourier series in order to calculate the Jacobian of vorticity ζ and the height of isobaric surface Z and also to solve the Poisson equation. As the preliminary report we explain mainly the detailed technique of our method how to treat and apply. It is also shown that the results of numerical forecasting will be improved, if we take shorter time interval of each step. In connection with this problem, the outline of the relay-computer (FACOM-100) which is available is written briefly.
