This paper presents an explanation of the average features of Evershed flow. Because the inertial force of Evershed flow is small compared to the gravity, Lorentz force and pressure gradient, the perturbation method could be used by adopting a small parameter which is the ratio of the typical dynamical pressure and magnetic pressure. Therefore, the dynamical processes associated with the global Evershed flow can be divided into a basic state and a perturbed state. The equations of the basic...

This paper presents an explanation of the average features of Evershed flow. Because the inertial force of Evershed flow is small compared to the gravity, Lorentz force and pressure gradient, the perturbation method could be used by adopting a small parameter which is the ratio of the typical dynamical pressure and magnetic pressure. Therefore, the dynamical processes associated with the global Evershed flow can be divided into a basic state and a perturbed state. The equations of the basic state are the same as those of mag-netostatic equilibrium between the pressure gradient, Lorentz force and gravity. The flow pattern of the theoretical results agrees well with the basic features of Evershed flow as shown by the Figures 3 and 4. The perturbed state describes the driving force for the Ever-shed flow. The Evershed flow opposes to the pressure gradient at the photosphere as the pressure in the umbra is less than that outside the sunspot. Based on the analysis of the present paper, this pressure gradient is balanced by the Lorentz force and gravity, and the driving force of the Evershed flow requires only a lower order of magnitude, and is not difficult to support from the centrifuge, perturbed Lorentz force or pressure gradient.

本文解释了Evershed流动的平均特性.因为Evershed流动的惯性力较小,与此流动相联系的动力学过程就可以分为基态和扰动态.基态解给出了压力梯度、洛仑兹力、重力之间的平衡关系,以及流动的规律.理论模型的流动与观测的Evershed流动一致.扰动态描述了Evershed流动的驱动力,讨论了一种具体情况.由于基态压力梯度已与洛仑兹力和重力平衡,平均Evershed流动的驱动力不大。
