摘要
文献[1]指出,温度平流能使大气出现浑沌态(chaos),从而产生湍流现象。在湍流发生时,理查孙数Ri总是和Re相配置的。大气运动状态的参数平面(R_i,R_e)可分为基本态O区,周期态P区,浑沌态T区,以及周期浑沌区T-P区(图1)。分析表明大气湍流可能通过周期倍分岔产生的。
The influence that condensation latent heat exerts on the atmospheric turbulence is studied with the Burgers-Chao Jiping equations, to which an item that represents the effect of condensation latent heat is added. A detailed mathematical analysis and some numerical illustrations are provided. The analytic results show that the condensation latent heat affects the atmospheric turbulence in a complex mode. The status distribution in parameter plane (Ri, Re) derived by Porf. Liu Shida is modified to coincide with more real situations of atmospheric status.
