Abstract: A brief summary of the achievements in the last years, of typhoon dynamics in China is reported. It consists of: (1) the instability theories of tropical disturbances and the causes of typhoon; (2) the dynamics of atmospheric vortexes and the motions of typhoon; (3) the diagnostic analyses of typhoon and the dynamical explanations of its structure; (4) the numerical simulations of typhoon;and (5) the laboratory simulations of typhoon in a rotating vessel.
