摘　　要：本文利用一个包括辐射、陆地的热量平衡,雪量的变化以及对流凝结和大地形的作用的两层球谱模式,模拟了冬季亚洲大陆冷高压的形成和发展过程。文中给出了大陆冷高压在源地形成、南侵和入海变性三个阶段的海平面气压场,对流层中部的温度场结构和垂直运动场特征,其结果与观测事实相一致。并模拟出冷高压发展所引起的副热带和热带行星尺度环流的变化。Using the two-layer spectral model involving radiation parameterization,continental heat e-quilibrium,convective parameterization and topography,we simulated the formation and evolu-tion process of the Asian continental cold high in winter.The distributions of sea-level pressure,temperature and vertical velocity in the mid-troposphere in the three development stages,i.e.for-mation,southward movement and transformation of the cold high,are given in this paper.The re-sults correspond with the observational facts.In addition,we simulated the variation of subtropicaland tropical planetary circulation caused by the evolution process of continental cold high.
