| 摘 要： | 本文采用数值试验方法、研究了冬季风和夏季风背景流场及跨赤道气流的相关因子。试验结果表明,西风带的分布与南北半球行星尺度锋区及赤道高温带的季节性经向位移相关。西风急流位置发生改变,可使基流与大地形强迫作用的非线性动力效应变化,导致大气运动趋向于不同背景流场的平衡态,形成了冬季风、夏季风的环流型以及跨赤道气流的季节特征。

| Abstract: | A p—σ incorporated coordinate 8-layer primitive equations model is adopted to investigate correlation factors of background flow field of summer and winter monsoons and the cross-eqatorial current.Results show that the background flow field of summer and winter monsoons and the cross-equatorial current are significantly correlated with the climatic position of the frontal zone; the joint effect of the westerly jet and the forcing of large scale topography. |
