中文摘要:

      观测事实表明,台风内核与外围的强度变化存在同步和不同步的复杂现象。为了研究这种现象,本文采用一个近似的控制方程组,应用尺度分析方法和非线性动力系统理论,定性地讨论了物理因子对内核与外围环流突变的影响。

英文摘要:

      The observed data show that the comlex situations of synchronous and asynchornous intensity variations can exist in the inner core and external part of typhoon. In order to study these phenomena, basing on the approximate governing equations, the scale-analysing procedure and the theory of nonlinear dynamical systems are used to discuss qualitatively the effects of some physical factors on the abrupt changing of circuladons in the inner core and external part.
