On Angervo-Petterssen's Method of Weather Forecasting

[摘要] From the theoretical point of view, the Petterssen's method must give the same result as usual one, in which the future position of the centre of depression is determined only by the extrapolating the past and present positions, without considering pressure field. The practical differences between them result from approximate calculations of differential coefficients and the results by Petterssen's method depend on the unit of numerical differentiations. A few examples of application to the weather forecasting in Japan are given
