Ⅰ. INTRODUCTION The crux of typhoon prediction is the prediction of typhoon track. In recent years many objective prediction models have been proposed, particularly the statistical-dynamical type has become comparatively the more effective one, e. g. the USA NHC-73, the Shanghai SD75 and the Zhejiang ZMI-80 have all proved to be superior to the pure statistical models in practice. In China, due to lack of

Let E(p, q; ε) denote the set of all systems (d~2x)/(dt~2)+p(t)((dx)/(dt))+q(t)x=0 with finite vairation coefficients p(t) and q(t) satisfying the following conditions: with p>0, q>0 and ε≥0. This paper draws the following conclusions.(A) For any two positve number p and q, there exists a positive number ε~*=ε~*(q/p~2) such that (ⅰ) for 0≤ε<ε~*, the trivial solution of any system of the set E(p, q; ε) is asymptotically stable; (ⅱ) for ε~*<ε, there exists a system of the set E(p, q; ε) whose trivial solution is unstable; (ⅲ) for ε=ε~*, the trivial solution of any system of the set E(p, q; ε) is stable, but there exists a system of the set E(p, q; ε) whose trivial solution is not asymptotically stable.(B) As q/p~2 increases from 0 to +∞ the function ε~*(q/p~2) decreases monotonically from 1 to 0.(C) Numerical table and graph representation of the function ε~*(q/p~2) are given for the use of engineers, physicists and control workers.
