Abstract
In this paper the author studied about a method of forecasting of the winter temperature by means of pressure gradients in November, in each directions about Gihu. The results are Y=0.24-0.12X, where Y is winter temperature and X denoted by the following equations: X=F•A+B•D when G>0, X=F•A+L•K when G<0 In the above equations A, B, D, K, L and G are numerical values calculated from the pressure gradients by suitable formulae under the consideration of following conditions: a) It is very cold in winter when the continental high pressure has developed in November. b) or when the high pressure has developed at central China. c) It is very cold in winter when the pressure has fallen in northeastern parts to Gihu districts in November. d) The winter takes moderate coldness when the pressure has fallen in southern part to Gihu districts in November.
The correlation coefficient between X and Y was calculated to be -0.75.
