As a result, a weak indirect cell is formed in high latitudes. By the 36th time step, the model atmosphere accomplishes the transition form one-cell circulation to two-cell circulation. There is a momentum source in the upper subtropical region. During the transition, the"polar westerlies jet"gets weakened and vanishes at the end, while the subtropical westerlies jet gets strengthened. At this two-cell stage, the generation and dissipation of westerly angular momentum do not balance each other, and the atmosphere is still at an unstable state with great surplus of angular momentum generation.
