| 摘 要： | 本文计算了一次西太副高进退过程中海上副高主体和大陆副高脊内涡旋动能的收支,并进行了对比分析得到,海上副高主体内的涡旋动能主要来自外部区域的辐合,动力性质明显;陆上副高脊在开始发展时,其涡动能源大部分来自涡能转换项,而在西伸北抬后,与南亚高压上下重迭,逐渐演变为热力性质,转换的涡旋能量不足以弥补辐散损失,最终导致西太副高的撤退。

| Abstract: | In this paper, a budget is computed for the vortex kinetic energy in the maritime main body (B) and continental ridgp (R) of the Subtropical High over the western Pacific in one of its ad-vance/feircat processes. Their contrasting analysis shows that the vortex kinetic energy in (B) mainly comes from the outer kinetic convergence. While in (R) it mostly depends on the conversion. With the High extending to the west and north to come under the South Asia High, (R) becomes more of thermodynamic one, resulting in insufficient vortex energy converted for the radiation loss and eventually the retreat of the subtropical high. |
