Abstract: In this paper,a modified Schördinger equation,one-dimensional,one-dimensional,constant out field,with balance between the created kinetic energy and potential energy:The corrective Schördinger equation i(∂ψ/∂t)=A(∂2ψ/∂x2)-iB(∂ψ/∂x) B=B0(∂T/∂x)is used to describe the behaior of the probability wabes in the six-monthly temperature and rainfall departure charts.It is found:C=2πA/L-B0(∂T/∂x);L→∞,C=-B0(∂T/∂x),C:wave belocity.A,B:constant.L:wabe length.The direction of probability wave is against the temperature gradient of outfield and the velocity values relate to absolute value of the temperature gradient for the siamonthly anomaly probability waves.The motion of waves conresponds to contraction of cold source and expand of heat source.This conclusion has been verified in practice.We have used these findings in MOS predictions of temperature and rainfall in spring-summer 1981一1985 in Jilin province with encouraging result.
