摘　　要：使用两种风场分解方法，计算旋转风和辐散风动能收支方程各项时空平均值，结果表明两者差异不大，具有一定程度的可比性。Applying two schemes by Shukla (1974) and Endlich (1967) to separate the horizontal wind into its divergent and rotational components,time-area averaged values of budget terms of KD and KR were calculated. The results show that there are agreement in the signs and rnagnitudes of budget terms. Thus,it does not affect the comparision.
