摘      要：Using the truncated-spectrum model of Burger’s-Chao Jiping equation, in which thetemperature advection is involved, we investigated the role of three parameters （Ri number, Renumber, Pr number） in occurrence of turbulence. It is shown that the turbulence may oc-cur only in the case of Ri2π2. If Pr is too small （Pr = 0.7 for the atmos-phere）, then the turbulence may occur only in the case of introducing interaction betweenbasic field and perturbation field or adding viscosity to the model. It is emphasized thatthe temperature advection plays an important role in turbulence occurrence. On the parame-ter plane （Ri, Re）, the atmospheric motion states can be divided into the O-region （basicstate）, the P-region （periodic state）, the T-region （chaotic state）, and the T-P region （cha-otic-periodic transition state）. In fact, this is appropriate. Finally, the physical reason of turbu-lence occurrence is discussed.
