The scale analysis on planetary scale motion in the tropical atmosphere shows that the equilibrium between the pressure gradient force and Coriolis force in the meridional direction is easily established, which is known as the zonally semi-geostrophic motion The semi-geostrophic adaptation process in which the inertial gravity waves play an important part is relatively quick The evolution process after the semi-geostrophic adaptation process is slow and controlled by the Kelvin waves and long Rossby waves

对热带大气行星尺度运动所做的尺度分析和物理分析表明：热带大气的行星尺度运动在y方向容易实现气压梯度力与Coriolis力的平衡，它称为纬圈的半地转运动。半地转平衡的建立过程，也就是半地转适应过程相对是很短暂的，它不需要考虑f=β0y随y的变化，因而主要依靠惯性重力波为频散；而半地转平衡建立后的演变过程相对是很缓慢的，它主要受Kelvin波和Rossby波控制。
