人工影响台风技术及其新想法

综述了前人在人工影响台风方面已有野外试验的技术原理、试验及其评价,然后从动力学的角度提出了人工影响台风的新方法,即通过流体力学的方法找到风场的一个极不稳定点,当该点受扰动后能使风垂直切变发生突变,切变突然增大很多,则可能破坏台风的暖心结构,使台风减弱,但其有效性和可行性尚需验证。

Typhoon Modification Technology and Its New Consideration

The theory, experiments and evaluation of typhoon modification were reviewed. And a new consideration of typhoon modification was proposed from the view of dynamics, which was finding an unstable extremum of the wind field by the method of fluid dynamics. After the perturbation of the extremum, the vertical wind shear increased sharply and abruptly, which could destroy the warm-core structure to weaken the typhoon, but the effectiveness and feasibility remain to be verified.
