The Objective Prediction of the Migrate High at Winter

Chia-Chung Yu

Abstract

　　Under the project named ”Objective Methods for Forecasting Prssure Systems and their Associated Weather Over Taiwan in the Cold Season”. the prediction of the movement and intensity of the migrate highs which come from middle and high latitudes are treated by several methods. In this paper the one named stepwise multiple correlation method is discussed, only.
　　In order to get a set of original data we reanalysis the surface and upper level chart, thru 1964 to 1973, every year from November to next May, than we use an electronic computer to finish all the works for statistical calculation and formulate the forecasting equations.
　　As presented in this report, six equations for forecasting the movement and three for intensity, for the next 24, 36, and 48 hrs prediction, of the migrate highs have been formulated.
